Thanks Margaret
As you know Ancestry don't show chromosome segments. However Ancestry does show shared relationships for most matches with good confidence or better, these all led back to Hannah Rowan and Joseph Thompson. I think my tree is quite accurate for at least 5 generations as my paper trails are confirmed by dna matches.
I have tried to avoid specific relationships on this thread as I was more concerned to ensure that my thinking was right in that the matches constituted a true connection to the Ross family. I do have another thread posted on the Irish Antrim forum (
http://www.rootschat.com/forum/index.php?topic=795503.msg6532340#msg6532340) detailing specific persons. I also wanted to make sure that the two threads didn't start to overlap and cause too much confusion.
You might be quite right about an extra marital relationship between the Ross and Rowan families as this would start to make some sense of the situation and the dna matches.
I am not familiar with DNAPainter but I will certainly check it out.
Once again many thanks for your thoughts and input.
