My grandmother was born in the early years of the 20th century and did maths at Cambridge, but didn't get a full degree, because women weren't awarded degrees there till the 1940s. She married in her 30s and had 3 children, and was a farmer's wife before teaching at a girls school (maths & physics.) I suspect these days, she would have gone on to do a PhD.
My grandfather's sisters who survived to adulthood also all had some form of higher education, in "sex-appropriate" subjects like nutrition, botany, English, dairying. So I come from a family where women's education was approved of, and they could afford it. I also have a letter from a Victorian ancestor, who fell out with her father in the 1860s because he didn't approve of her going to college (she did anyway; they later made up.)
On the other side of my family, I'm the first to have gone to uni, so I think the differences are more marked there, despite her being nearly a generation younger than my other grandmother. She left school at 14 and worked in a factory until she was called up for the services at 18 (early 1940s.) But I think there's also more contrast because she came from a city and always lived there, whereas my other grandparents had been on a farm, and my father was a farmer, so there was all that in common, and we saw a lot more of that side of the family when we were children. It did all mean I was brought up expecting to go to uni, and there was no truck with ideas like girls can't do maths and science (which I also didn't get at school, which was single-sex for secondary.) It did take a bit of mental adjustment at uni that there were quite a few people who were the first in their families to go to uni (1990s) - I thought a cousin of my generation was a bit of a rebel for not going!
