The 1776 is my 4th Great-Grandfather and the 1742 is my 5th great grandfather. The 1742 had 10 children or lines. Three of those lines tested YDNA. One has a genetic distance of 1, one has a distance of 3 and my line has a distance of 5 (I was not tested).With the YDNA and the circles it has made me think that the 1742 is not my 5th great-grandfather but someone (say a brother etc) that ties into the line behind the 1742 ????????
