> What kind of dad was this man then? What kind of connection did he build with his daughter?

I'm not sure whether you intended this, but (since we're discussing biology here) this is really two possible connections. One is that she grew up with a dad who was (apparently) a gigantic asshole. The second is that she got 50% of her genes from a gigantic asshole. Or more charitably, from someone who wasn't emotionally a great fit for 20/21st century capitalist society.

Before any study counts such things as evidence of weird epigenetic effects, it had better do a really solid job of taking these (19th C) effects into account, to see if there is anything left. And that's pretty hard to do.
