About Me

Roberta Estes has been a professional scientist and business owner for 25+ years, (BS Computer Science, MBA, graduate work in Geographic Information Systems), as well as an obsessed genealogist since 1978. 

In 2005, reflecting her interest and expertise in genetics for genealogy, she formed DNAeXplain, a company providing individual analysis of DNA results and genealogical assistance.  Please visit the web site at www.dnaexplain.com

In 2009, DNAeXplain and Family Tree DNA teamed to jointly offer Personalized DNA Reports for customers.  http://www.dnaxplain.com/shop/features.aspx

In 2000, thanks to FamilyTreeDNA, the infant scientific field of DNA for genealogy emerged, allowing DNA to be used to trace individuals to common ancestors.  With traditional genealogical records already researched to no avail, and several brick walls needing to fall, Roberta was one of the early DNA surname administrators and pioneer adopters of DNA analysis for genealogy.  

Roberta manages over 20 surname projects and is the founder of the Lost Colony DNA research projects.  Her regional Cumberland Gap Yline and mitochondrial DNA projects have several thousand participants.    She also co-administers several Native American and African DNA projects and serves in an advisory capacity for the Melungeon project and other groups. 

Roberta speaks and writes widely about DNA and genealogy, including the Native Heritage Project at www.nativeheritageproject.com.

  1. I’ve been using DNA painter to map out cousins listed at MyHeritage. On chromosome 15 I noticed 35 cousins starting at 20,004,966 with short matches between 15 – 25 cM. What could that mean?

    • In some cases, they may be accurate, and in some cases they maybe noise. It’s helpful to test other family members to see if they have the same occurrence on the same chromosome which increases the likelihood that it’s accurate.

  2. Hi Roberta, I’ve made some tests at FTDNA (waiting for the BigY now) and I’d like to fully (or nearly) understand all the mechanics of haplogroups and SNPs. I see that there are many groups with many associated SNPs (R1b-M269 has 97 or so). A haplogroup should be defined by one SNP, right? Having so many SNP means that all but one correspond to groups further down the tree that are not yet defined, right? But … 97? It’s a bit confusing to me.
    Can you shed a little light on this subject please? Thanks in advance.
