Re: New Big-Y files needed

Charles Thomas

Hello Jared, Thomas, and everyone,

I've found the Matching Segment Search very helpful at It's available via the Tier 1 utilities which requires a $10 fee for one month's access. It's helpful in finding others who match at the same segment and therefore have a shared ancestor/ancestral couple. It can be tricky, however, determining which match is from which copy (maternal or paternal) of the particular chromosome unless one has a parent whose results can be "phased" against your own.

Best wishes for the new year,

Charles Thomas

I'd certainly recommend that anyone that has done autosomal testing to
upload their results to This site provides a great way
to find matches from all of the major testing companies. If you've not
used it, I wrote a tutorial that may be helpful -
Genetic Genealogy using GEDmatch An Absolute Beginners Guide. by Jared Smith. Please contact me if you have any corrections or clarifications. Overview

It would be a good idea to check your GedMatch one-to-many list for
the surnames of folks in this group. It's most likely that our shared
direct male line ancestors are too far back to have shared autosomal
DNA from them, but it's possible we're related in other ways.
