Episode 217 – The Golden State Killer and Your Genealogy and DNA
Genealogy Gems Podcast Episode 217
with Lisa Louise Cooke
In this special episode, host and producer Lisa Louise Cooke takes a look at the Golden State killer, one of the most notorious crime sprees in recent memory. She’ll talk about the role that DNA testing played in an ultimate arrest, and the impact that these events are having on genealogists and the use of DNA in genealogy.

“The Golden State Killer,” 48 Hours episode on CBSNews.com (44-minute episode)
Between 1974 and 1986, activities attributed to the Golden State Killer include at least 12 murders, more than 50 rapes, and over 100 burglaries in California from 1974 through 1986.
The criminal’s methods led some investigators to believe that these differently-labeled criminals were very likely one in the same.
In 2001, DNA definitively linked several rapes in Contra Costa County believed to have been part of the East Area Rapist series, a series of murders in Southern California.
In 2011, DNA evidence proved that the Domingo?Sanchez murders were committed by the same man, known as the Golden State Killer.

Caution: In this episode, Lisa shares her personal opinions on the use of technology for crime fighting and the implications for DNA testing for genealogy. She encourages everyone to do their own homework and make informed decisions in line with their own values, opinions, and objectives.
Reality check: “The only way to ensure privacy is to never put anything of any kind online. Just like the only way to ensure you will never be in a car accident is to never, under any circumstances, get in a car.”

Several ways we already use DNA matches:
- Genealogists use to build family trees
- Adoptees use to identify birth parents (or other biological relatives)
- Orphans trying to find long lost siblings and relatives
- Anyone looking for estranged family members
- Researchers identifying unidentified human remains, including POW/MIAs

“When you test, you are also making a decision on behalf of your parents, siblings, children, grandchildren, and future descendants. Regardless of good intentions or stated ethics codes in the genealogy community, it isn’t possible to write and get the express permission of everyone who could be affected by you having your DNA tested.” ?Lisa Louise Cooke

Ancestral Landmark Discovery Using Google Earth for Family History
Thom learned how to use Google Earth for family history after watching my free Google Earth for Genealogy video, and then made a landmark discovery: his ancestors’ pond, business and a photo of his family at work.
This Using Google Earth for Family History success story was recently sent in by Thom, a young genealogist who blogs at The Millennial Genealogist. Be sure to click on the picture that goes with his story–it’s really neat.
Thom’s Google Earth Story
“I am writing to share with you a TOTAL (and entirely unexpected) success in using Google tools for my research.
By way of introduction, I am a young genealogist (age 21) from Massachusetts. I recently discovered your podcast and have been working through the archived episodes on my daily 1.5 hour commute.
I watched your Google Earth presentation last weekend, and had some time to try your tips out after work today.
My family has strong roots in North Attleboro, Bristol County, Massachusetts. So I decided that my first task would be to find a good historical map to overlay. A quick Google search yielded a 1943 USGS map of the greater Attleboro area on the University of New Hampshire website. Some quick adjustments left me with this great result:
My curiosity having been piqued, I began exploring the map. I know that two sets of my second-great-grandparents, Bert Barrett and Grace Freeman, and James Adams and Elizabeth Todd, all lived near Oldtown Church (presently the First Congregational Church). I zoomed in:
Looking at Google’s current street names, Oldtown Church is right by the intersection of Mt. Hope and Old Post (you’ll note the small cross). Now keep following Mt. Hope Street – do you see what I see? Todd’s Pond! I just knew this couldn’t be a coincidence. So I went straight to Google again:
And the very first result, a page within a Google Book on the history of North Attleboro, was astonishing:
“In the days before electric refrigeration, North Attleborough’s homes and stores relied upon ice harvested from either Whiting’s Pond or Todd’s Pond (depicted here).
By the time this 1906 photograph was taken, farmers George, Henry, James, and William Todd found selling ice more profitable than farming and founded the Oldham Ice Co.
Todd’s Pond was located on the westerly side of Old Post Road near the corner of Allen Avenue. The Oldtown Church is visible in the background.”
From North Attleborough by Bob Lanpher, Dorothea Donnelly and George Cunningham (Images of America series, Arcadia; click here to see the picture that goes with this photo, along with other pictures he found with a follow-up visit to the area.)”
Mentioned by name are great-great-grandmother Elizabeth’s four brothers, George, Henry, James, and William Todd. What a spectacular find!
I plan to reach out to the local museum that prepared the book to see if they can provide a better copy, and even additional media should I be so fortunate.
In short, I wanted to take a moment to say THANK YOU so very much! Had I not been exploring Google Earth at your suggestion, I’m not sure if I ever would have ever noticed “Todd’s Pond.”
The Power of Google Used for Genealogy
I hope you are using Google Earth for family history! Paired with Google Books and the rest of rest of Google’s genealogy tool box, it can help you unearth fascinating facts about your family history.
Here’s an image I found (using Google Images) that shows the process of harvesting ice, a profession long gone with the age of modern refrigeration.

The ice trade around New York; from top: ice houses on the Hudson River; ice barges being towed to New York; barges being unloaded; ocean steamship being supplied; ice being weighed; small customers being sold ice; the “uptown trade” to wealthier customers; an ice cellar being filled; by F. Ray, Harper’s Weekly, 30 August 1884. Public domain image, Wikimedia Commons. Click to view.
Resources for Using Google Earth for Family History
In my book, The Genealogist’s Google Toolbox, I’ll teach you how to use Google Earth for family history, along with Google Books, Google Images and more.
My Google Earth for Genealogy video tutorial series will then round out your education.
Both are packed with step-by-step instructions and examples from my own family history research to inspire you. Google and all its powerful tools are FREE. Why not invest some time in learning to harness its power?

Digital Family History Books at Your Fingertips
Do you sometimes wish you had your own enormous library of family history reference books? Or do you dream of how nice it would be to live near a major research library? Or do you ever wish the family history book in your hand had been better indexed so you could turn exactly to the page you need?
Digital books essentially make these dreams come true by putting books at your virtual fingertips with fully-searchable text (no indexes needed!). And FamilySearch’s digitizing project (a partnership with Allen County Public Library and other major research libraries) now has 100,000 titles scanned, more than 80% of which are online.
If you haven’t used the free Family History Books section at FamilySearch.org, you should go browse it right away. According to a press release, “The majority of the books online are family histories, with a smaller portion made up of cemetery records, local and county histories, genealogy magazines, and how-to-books, gazetteers, and medieval histories and pedigrees.”
Your family may be hidden in one of these books – and they’re now searchable with just a few keystrokes. What keywords should you try? Of course, your ancestor’s surnames, including variant spellings. Also search for other words associated with their lives: the name of their hometown, church, school, employer or industry, ethnic group and even surnames of friends or associates.
You can contribute to FamilySearch’s digital books library, too. If you are attending the Federation of Genealogical Societies conference next weekend in Fort Wayne, Indiana, you are invited to bring your own titles for scanning by FamilySearch and Allen County. They are most interested in autobiographies and biographies containing genealogical material; family histories with genealogical information; indexes to records; local and county histories; and yearbooks.
To contribute a digital book, FamilySearch says: “Permission must be obtained from the author or copyright holder before copyrighted books or photos can be scanned. (Most books that were published before 1923 are in the public domain and do not require permission.) There is no limitation on the size of a book for scanning, but photos should not be larger than 8.5 x 11 inches.”
3 Sources for Historic Maps that May Surprise You
Old maps are an essential tool for discovering more about your family’s history. If you have exhausted more traditional sources, here are three places to find maps that may surprise you.
#1 Surprising Finds within the David Rumsey Map Collection
You’re probably aware that the David Rumsey map collection website is a terrific source for old maps. But you may be surprised by the variety of maps, some which you likely don’t come across every day. Here’s a fun little tactic I took today to see what it may hold in store beyond typical maps. A search of the word neighborhood reveals that their holdings go well beyond traditional maps. Here’s an example from San Francisco showing a neighborhood in its infancy:
And the image below depicts the Country Club district of Kansas City in the 1930s. If your family lived there at that time, this is a real gem.
#2 Google Books
If you think Google Books is just books, think again. Historic maps, often unique and very specific, can often be found within those digitized pages. Try running a Google search such as: neighborhood map baltimore.
Click the MORE menu and select BOOKS. Then click the SEARCH TOOLS button at the top of the results list, and from the drop down menu select ANY BOOKS and then click FREE GOOGLE BOOKS:
Select a book that looks promising. Then rather than reading through the pages or scanning the index, save loads of time by clicking the thumbnail view button at the top of the book. This way you can do a quick visual scan for pages featuring maps!
When you find a page featuring a map, click it display it on a single page. You can now use the clipper tool built right in to Google Books to clip an image of the map. Other options include using Evernote (free) or Snagit ($).
#3 Old Newspapers at Chronicling America
http://chroniclingamerica.loc.gov/
Like Google Books, the digitized pages housed at the Chronicling America website contain much more than just text. Old newspapers printed maps to help readers understand current events like the progress of war or the effect of a natural disaster. This map from The Tacoma Times in 1914 shows a map of Europe and several quick facts about the “Great War,” World War I:
Here’s one more example below. A search for “San Francisco earthquake” at Chronicling America brought up this bird’s eye view of San Francisco at the time of the major 1906 earthquake. Articles below the map explain what you’re seeing:
