Unless there is a family tradition of a non-paternity event, there really isn't much reason to look for matches with other surnames until testing confirms a non-paternity event. Even with a family tradition, the surname-haplotype combination may not be in any of the databases.

To confirm a non-paternity event during the period when documentation is feasible, he would need to test his most remote documented cousin. If they are not close matches, he would need to test a third to determine which line had the non-paternity event. He would also need to test other branches to try to pinpoint the generation when the event occurred before looking into the paper trail.

If they match, he has determined the ancestral haplotype. If they are only close matches, he will need to test another. If he has reason to suspect that the non-paternity event occurred with the progenitor or earlier, comparing ancestral haplotypes is much easier, since recent mutations have been eliminated. However, establishing the matching family as the correct one is very difficult, but might be worth pursuing. I would upgrade both to 48 markers (FTDNA + DNAH or RG) or more (with Biotix) before spending the time pursing such a match, though.

This participant says he hasn't found any close matches on Y Search, much less with any other Clarks.
