Contact Us Now to Interpret Your Genealogy DNA Testing

Using your DNA test results from, FTDNA, 23andMe or MyHeritage we can group your DNA matches into probable family clusters and provide clues as to the shared ancestor in each of the family tree groups.  Your genealogy DNA testing can be used to enhance your family tree, confirm or refute family tree lines, and correct mis-attributed parentage.  For adoptees, your DNA results can be used to fill in the unknown parentage of your family tree lines. 





Family Group Analysis

This is very helpful for confirming or refuting your paper trail family tree, and filling in missing lines, including instances of adoption
We will provide you with a spreadsheet covering: 

  • An analysis of at least your top 25 matches
  • A grouping of these matches into probable family lines
  • A review of the above matches in conjunction with matches from other sites where you have tested or uploaded your results
  • An analysis of the potential common ancestor(s) for the family line groups
  • Recommendations for next steps, such as additional testing, matches to be contacted or researched

An DNA test is a prerequisite for the Family Group Analysis; please contact us for information regarding the analysis of other DNA tests

Fee is $80; additional genetic genealogy research can be contracted at a fee of $25/hour
