Given enough markers (we may be reaching that with 59 markers) or a rare
enough haplotype, Y-DNA might actually be effective at proving or at least
being very suggestive of paternity. Given other information about the
father (say lastname and state?) you can be pretty well sure of the
connection with him or one of his brothers or father.

I'm thinking a full mtDNA sequence would also pretty well narrow down your
options for mothers as well.

It probably wouldn't stand up in court, though. ;)
