Glad it helped! I understand how the DNA can move your research along-- it has helped us break down some solid walls that we never thought would be moved. By any chance have you or your sister uploaded to Gedmatch? My dad's DNA would be my farthest back Cooke- in case you have anyone uploaded on gedmatch, my dad's kit number is A515419 and he is Robert Donald Garner on my public tree here on ancestry, garner_2012-05-10 (yes, terrible name, I didn't realize that filename would become my tree name! LOL). His DNA is also attached to that tree here on ancestryDNA. I hope you find your connection before another 27 years! If I can help in any way, let me know. My great grandmother was Martha Evelyn Cook Garner.
