His mum had 1 sister and 3 brothers. On his dad's side there is 1 aunt with 4 boys, the others had an even mix. His mum's siblings had even spilt of boys and girls. We have 3 boys, but there seems to be no history of gender dominance on DH's side of the family.
On my side, in my generation there was a huge dominance of girls for many years, then the amount of boys born seemed to catch up. In my children's generation there are more boys than girls, but then I have 3 of them. My mum is one of 6 (3B, 3G), my dad has 2 sisters.
I think I have 3 boys because I have a high testosterone. I read an article on it years ago when I was a teenager and felt I fit the symptoms back then. It doesn't seem that it is genetic though.
