Inbreeding "complications", takes over a hundred years of constant inbreeding. This is a problem they have in countries where they normally marry "in the family", (cousins), to "keep the money in the family". (Turkey)
The "issues", related to birth, are still marginal. They result in mostly still-born or self-abortions. The percentages of other complications are like 2-5% greater than normal birth defects from breeding with non-family.
Movies and fiction made it out to be worse than it is, in reality.
However, the father "having the bride", was not uncommon. If the guy paid for a virgin (Dowry/Paid), he got one. But the father still "gave away", the bride. {Got her to take his seed}.
In a family, back in the day... you usually only married-off the good looking healthy children, which was usually only one boy and one girl... The first-borns. The ugly ones were usually sold-off for "slavery", (for girls, that was sex slavery or prostitution.) But not until they were taught how to have sex for good money, by daddy-pimp. (Not an issue in bibles, because they were clean virgins, not whores yet... Also, it's what men wanted, and men wrote the bibles. That is why the first thing in all bibles is about men ruling over women and women shutting-up, and not preaching.)
However, "fear of birthing a deformed child", from incest is usually not a fear, because they usually don't fuck to reproduce. They fuck to fuck, or to express intimate bonded love. (More to the prior, in the most "talked about cases"... Since, those loved don't talk about it.)
I love when people say... "Not in my family"... I call bullshit, 100%, without a doubt. It's like the news... they don't tell you when you are a kid, that people are killing people by the thousands and other countries have the power to drop bombs that can wipe-out entire cities from across the globe... Until they get older and figure that shit out. Then, to them, it looks like the world is falling to shit suddenly... No, it was always shit, you just didn't know the shit was under the carpet.
Same with these "skeletons"... Your mom and dad don't tell you that they fuck... Why the hell would your sister tell you that she is fucking dad? They already know you are creeped-out by it. You are the last person anyone would tell anything to. Also, you have a big mouth. (Not you OP or other guy... Just saying, to those who say "not in my house".)
