Except for major figures, the Bible mentions marriages mostly in form of lineage (And X begat y, and y begat z)
Homosexual unions do not figure in here, because they are, as they say, without issue. This doesn't mean that there were no gay men in the Bible, thugh it seems probable to me that male gays were secretive, being as they did not wish to be executed, and Lesbians lived in a fairly segregated society and probably scissored one another for generations unbeknownst to the men, perhaps in the many periods when they were deemed "unclean".
