The Bolling DNA Site is the best I have seen on line, but only as good as the information people have given them.
When a person turns in their sample should only name your oldest known ancestor from fully documented material.
Three Kit #1926,23213 & 895 their DNA profile they should be under Group 3 (my group).
However the emigrate ancestors they are reporting found under Group 2 Thomas Boulding of "Swan" Found in Todd Bolen book under Fh743 & Fh 665.
Who was their real ancestor I have no idea, but not the one reported.
