What I just described, no one does.
Well?
Same sex marriages, sure. Sometimes?
I'm sure I saw (on tv) a lesbian wedding where both brides were given away by their fathers, arriving simultaneously at the alter.
Regardless, in TNG we saw Data give Kieko away.![]()
Well, whatever makes people happy.
But for the giving away thing, it only makes sense if it's someone that raised you or took a significant part in raising you.
