AncestryDNA Results Improving for Jewish and Hispanic Ancestry

dna_magnifying_glass_300_wht_8959Ancestry.com has improved the ability of AncestryDNA to find good matches for Jewish, Hispanic and other ancestries that maybe weren’t so precise before. Here’s the lowdown, quoted liberally from Ancestry.com’s press release:

The problem: Predicting genetic relatives among customers of Jewish and Hispanic descent and some other groups. “In DNA matching, we are looking for pieces of DNA that appear identical between individuals,” says the release. “For genealogy research we’re interested in DNA that’s identical because we’re both descended from a recent common ancestor. We call this identical by descent (IBD). This is what helps us to make new discoveries in finding new relatives, new ancestors, and collaborating on our research.”

“However, we also find pieces of DNA that are identical for another reason. At one extreme we find pieces of DNA that are identical because it is essential for human survival. At the other, we find pieces of DNA that are identical because two people are of the same ethnicity. We call these segments identical by state (IBS) because the piece of DNA is identical for a reason other than a recent common ancestor. This, we have found, often happens in individuals of Jewish descent.”

“The challenge in DNA matching is to tease apart which segments are IBD, and which ones are IBS….Most Jewish customers find that we predict them to be related to nearly every other Jewish customer in the database….Detecting which cousin matches were real and which ones were bogus has always been a challenge for these populations.”

First step toward a solution: “By studying patterns of matches across our more than half a million AncestryDNA customers, we found that in certain places of the genome, thousands of people were being estimated to share DNA with one another–likely a hallmark of a common ethnicity. Our scientific advancements… have allowed us to effectively “pan for gold” in our matches–by throwing out matches that appear to only be IBS, and keeping those that are IBD.”

“While the problem was more pronounced in customers of Jewish and some Hispanic descents, we observed this problem across all ethnic groups.  So, all customers will see increased accuracy of their DNA matches, and significantly fewer ‘false’ matches.”

AncestryDNA results with better matches found by this method “will be available in the coming months,” says the release. They plan to email existing customers when results are ready.

We Dig These Gems: New Genealogy Records Online

Each Friday we share a list of selected new genealogy records online. Watch for records in which your ancestors might appear–and get inspired by the kinds of records that may be out there waiting for you to discover. This week: Australian cemetery records, British military officer deaths, various U.S. passenger lists and North Carolina marriage records.

AUSTRALIAN CEMETERY RECORDS. Two million indexed records have been added to the free Australia, Queensland Cemetery Records, 1802–1990 dataset at FamilySearch.org. According to the site, “The records include an index which combines several other indexes, cemetery transcriptions, burial and other records from cemeteries in Queensland….Cemetery records are especially helpful for identifying ancestors who were not recorded in other records, such as children who died young or women. They may also give clues to finding more information. In Australia, the first cemetery is reported to have been in Sydney in 1788.”

BRITISH MILITARY OFFICER DEATHS. FindMyPast’s new dataset, Royal Artillery Officer Deaths 1850-2011, lists the details of over 17,000 commissioned officers who were killed or died during the campaigns in Kosovo, Bosnia, Borneo and Iraq as well as the First and Second World Wars. It is estimated that since the regiment’s formation in May 1716, over 2.5 million men and women have served with the regiment. Each record includes a transcript of details found in the original records.

US PASSENGER LISTS. Browsable images were added to several existing US immigration records. Click here (and then scroll down) to view a table that has links directly to these datasets:

  • For San Diego, CA:Airplane Passenger and Crew Lists, 1929–1954 and an apparently segregated Chinese Passenger and Crew Lists, 1905–1923;
  • San Francisco, CA Passenger Lists, 1893–1953;
  • Key West, FL Passenger Lists, 1898-1945;
  • Minnesota Passenger Lists, 1910-1923;
  • New York City, NY Passenger and Crew Lists Soundex (meaning an index based on how a name sounds), 1887-1921; (this is actually a new image collection)
  • North Dakota Manifests of Immigrant Arrivals, 1910-1952 (this is also new).

NORTH CAROLINA (US) COUNTY MARRIAGES, 1741-2011. This new dataset on Ancestry “includes images of marriage bonds, licenses, certificates, and registers from 87 different counties.” According to an Ancestry blog post, some marriages have multiple records in this collection, like a bond and an indexed marriage record. This record set may be particularly useful for those tracing African-American marriages, as they “reference the joining of couples living as man and wife dating back to 1820, and possibly earlier…. Sometimes they also include the names of their former owners.” There’s a free, similar-looking dataset at FamilySearch, but the dates aren’t as extensive (it covers 1762-1979).

Tip: When searching within record sets like these, read the record collection description! Sometimes you are just seeing a partial collection that is being updated on an ongoing basis. Some years or locales may be missing from an otherwise complete record set.

When you have questions that aren’t answered in the record collection description online, Google them! Use keywords like the type of record (“marriage records”) and the missing locale (“Burdett County”) to see whether other sites can lead you to these records or confirm that they don’t exist.

CROATIA CHURCH BOOKS. Nearly 3 million indexed records have been added to FamilySearch’s free collection of Croatia Church Books, 1516-1994. Browsable images are already online. According to the collection description, “Records of births and baptisms, marriages, deaths and burials peformed by priests in Croatia. Includes vital records of Jews.

PENNSYLVANIA CIVIL WAR MUSTERS. Ancestry subscribers can now search Pennsylvania Civil War Muster Rolls, 1860-1869. Says Ancestry, “This collection includes muster out rolls, arranged by regiment and thereunder by company. They list the soldier’s name, age, rank, unit, regiment and company; the date, place, and person who mustered him in; the period of enlistment; and the name of the commanding officer. Other details can include where the soldier enlisted, whether he was drafted or was paid as a substitute, pay earned, money owed to the U.S. for clothing or missing equipment, promotions, capture by the enemy, illnesses, and bounty paid and owed. At the end of the musters, transfers, deaths, and deserters were often listed, typically with details about the circumstances (e.g., where and when transferred; cause, date, and location of deaths; dates and places of desertion, etc.).”

Here’s a tip: Always read the descriptions for online collections you are searching. The descriptions generally tell you the source of the records; which records are included/missing; what genealogical data you may find in them and tips for searching the dataset. Some websites also suggest related databases. This tip comes to you courtesy of The Genealogist’s Google Toolbox by Lisa Louise Cooke, freshly updated and completely revised for 2015!
