Thank you for your comments, Diana.
In my situation, I have already proven that the two gentlemen in question
are brothers, or at least half-brothers as they share the same mother.
Should the DNA match, then I think it would be very likely that they had the
same father, though the fathers could be brothers or cousins.
In any case, I think I have decided against the idea of having my cousin
tested, as it is MY heritage that I am after, not that of my cousin (or half
cousin). It appears that all I need to do is have myself tested with 67
markers, and then I can look for a match with other surnames, starting with
the "target" surname hinted at by my great aunt's middle name.
If I get a match, I can then use conventional methods to try to identify the
actual individual in question.
