Clark-38342 and Clark-6831 do not represent the same person because: It actually appears that we might be talking about father and son, here...I would say that there's not enough matching to suggest a merge.
Clark-38342 and Clark-6831 appear to represent the same person because: it appears that Clark-38342 was created in error. It looks like his marriage date was entered as his birth date. The source listed on his profile confirms this. I adopted this profile today so that a merge could take place.
