My brother recently had his Y DNA tested and is grouped as I-BY22819, which appears to be of Scottish origin. We have traced our McIntyre line only back to the mid 1700s in Leesburg, Virginia, and would like to now figure out the earlier Scottish ancestors. At Family Tree DNA, in the McIntyre DNA Project, it appears that we may be related to Duncan MacIntyre, born 1640 in Glenoe, Scotland, First Chief of Glenoe, but we have no information to back up any actual ancestors who connect to that line.
