Well, the first step is to determine what country and, if possible, what
city the person lived in around that time.

Next, share with others (say, this mailing list) the reasons that you
believe this person did or did not convert, along with any other
information you think might be useful--such as the names of relatives,
spouses, etc.

With such information in hand, some of us might be able to give you
assistance.
