And what was dovid hamelech’s yichus? born out of incest (moav and lot) and deception (tamar and yehuda)…
Avraham Avinu? (idol merchant father)
There was a good ruse I heard once (maybe someone can quote it) where a Rabbi asked a group of girls “Who would you rather marry?
1) A guy who is estranged from his siblings and obsessed with his good looks
2) A convert who doesn’t know a word of torah”
… There are two others
(btw, 1 is yosef, 2 is R’ akiva)
disclaimer- not saying marry a bad person, just saying yichus doesn’t matter
