Go to Search on the Find drop-down menu, and input the name. You should get a list of all the WikiTree profiles with that name. If you know the birth date you're looking for, then sort the list by birth date.
Good luck!
Edit: Now I see you're looking for a pretty ancient profile. There are several with the same name in a somewhat similar time frame, and it looks like the others could use more research. So as I said, good luck!
