Grandma Katie's Ancestors And DNA

Based upon DNA submitted by my brother at Family Tree DNA and a fortunate match with Grandma Katie's nephew's daughter (through Pearl Johnson, Grandma Katie's sister, and Robert Logan, Pearl's son), I was able to select persons who matched both my brother and Pearl's granddaughter, and make the assumption that those persons had a mutual ancestor(s) somewhere in Grandma Katie's family tree (as opposed to the Powers (paternal) tree or the Garrett (my maternal grandfather's) family tree).
