Comparison of Relationship Report to ftDNA prediction

Click to enlarge my Relationship Report

In my last post, I talked about my paternal grandmother's new autosomal DNA match. We found our common ancestors to be Henry TATE and Sarah NETHERLAND. Family Tree DNA predicted that this match and my grandmother were 5th to Remote Cousins.

I asked this match to send me her direct line descendancy and then I entered them into my RootsMagic software, starting from her descendancy from Henry Tate and Sarah Netherland through their daughter Mary Tate Davis. I then did a relationship comparison and learned that my grandmother and her match were

6th cousins, 1x Removed

Being 6th cousins would normally mean that they share the same 5th great-grandparents; however because they are 1x removed, their common ancestors are 5th great-grandparents for one of them and 6th for the other.  

Relationships can be compared in RootsMagic by going to Tools / Relationship Calculator. Then enter each person and click the "Calculate" button:

Relationship Reports, like the one displayed here, can also be generated in RootsMagic. 

Click on the Reports Menu / Select Charts / Select the Relationship Chart. Select the people you want to add to the chart. Select the options you want - Birth and death years, Marriage Date and give it a Title. Then click the Generate Report button.

You can then save the Report as an RTF or a PDF. I like to save them as an RTF and that way I can add text to it later if I want. The RTF contains only a bitmap of the report - the report itself cannot be edited but text can be added to it. 

This process has been helpful in determining if the connection found is linked to the DNA. If the relationship determined in my RootsMagic software matches up with what ftDNA predicted, then there's a good chance that the DNA that is shared between us and our match was inherited from these common ancestors.
