JewishGen Discussion Group #JewishGen Unknowingly marrying a sibling #general


Hello! I'm a little behind on e-mail reading, hence the late post...

This should be even more of a concern for people conceived through
anonymous donor gametes. One man can, in theory at least, sire a great
many children through such donations, and all would be half-siblings to
each other. The same is true -- to a much lesser degree -- for a woman
who donates eggs. Since the resulting children don't receive much
information about their DNA donors (assuming they are even told the truth
about their conceptions), this makes unwitting marriage to a sibling a
very real possibility, even if it's still rather unlikely.

Makes you young folks wonder just how much you know about your spouse,
doesn't it? <wink>
