23andMe Addresses the ‘Show Close Relatives’ Settings — Finally!

Today DNA testing company 23andMe put a new policy into effect concerning DNA Relatives. Until today, June 5th, 2014, someone would have to check a box in their profile to agree to ‘show close relatives’ before they saw relatives closer than 2nd cousin such as half-siblings, parents, children, aunts and uncles, or nieces or nephews.

A Study on French Canadian DNA and the Implications for Genetic Genealogy

A Study on French Canadian DNA and the Implications for Genetic Genealogy

Ethnicity Calculators The Big Three genealogy companies (Ancestry.com, 23andMe and FTDNA) all have ethnicity calculators.

The problem with any search engine is that if you narrow the search to tightly match a keyword, you will eliminate the inevitable errors that lie in records created by human beings, variations in name spellings, typos in birth dates, or paperwork that is misfiled.

Cousinhood

Cousinhood

What is a Cousin? Most of us have one or more in our modern nuclear families. We generally think of them as our aunt’s or uncle’s child. Some of us even are familiar with a second cousin who is the grand child of our grandparents but is not our sibling. But genealogists talk about more distant cousins and it’s often hard to distinguish what genealogists mean by the various terminology. I hope to clarify that here. MRCA To … Read entire article »
