Hi! Do you know where any of these family members lived? Washington DC? NY? A location in the late 1800's would help a lot, I think. I don't have any McCrackens in my data base, but I may have her husband (wife unknown). The Whelply spelling, without the final 'e' before the 'y' is significant, if it's truly the way they spelled it. I know of only one branch (mine) that spelled it that way.
