Yes, I have had my DNA tested, Y only. Mine was part of the Clan MacFarlane study in 2007, but I had been interested in for a couple of years prior to that. In the early days of DNA testing I was marginally worried about privacy, but as I learned more about it am quite happy to share results. Now I am seriously considering doing a mtDNA profile. Tom
Currently I have been able to collect paternal DNA markers for 4 of my family surnames: Horne, Jaynes, Gibson, Hickman. I also have maternal DNA markers for myself and one of my cousins, now that is a whole different ball game, changes in maiden name to married names makes it next to impossible to find direct linkage on some of my family lines. My maternal DNA is the only one I have been able to take back to 1765. Hope to someday find others who are of this DNA lineage.
