There were several Julius Coles in the area back then--the original Julius literally had dozens of grandchildren. I don't have them all recorded, but those Coles were fruitful and multiplied, that's for sure. And my Coles are all very tall and lanky. My great-grandfather had six brothers, and I think they were all over six feet. I even had two great-aunts (his daughters) that were six feet tall. So your great-grandpa came by it naturally!
