Where: France.
I would very much like to know what homes were like in the 12th century, how people acted, what the role is of the women in the home, how people were treated, and how the "high-class/rich" were treated over those lower than them. Pretty much anything I can learn about the people. Not specific names, just people in general.
I play around with vampire myths a lot. I'm always trying to make vampires more logical.
However, they're illogical no matter what you do to them. xD
I have a vampire encyclopedia.
Homes: Pretty crappy. The poor lived in houses made of thick timbers and and roofed with pitch-covered hay, a huge fire hazard. The rich lived in drafty castle-forts or just big elaborate houses that were also fire hazards, they could just afford fire in a fireplace more often (it was outside fire that was the problem).
How people acted: That's pretty broad. People tended to remember you and many people were nice and helped strangers, but then there were also thieves, pickpockets and murderers who could take advantage of people and the lack of intelligence. Only clergy could read back then and they were very superstitious.
France was fighting Britain back then and France was smaller, most of it was British territory.
Roles of women: Be a virgin on your first wedding night, don't talk back, sew, clean, don't blaspheme, pop out babies. Cover your hair unless you're a whore. Same with keeping it long. Usually this applied to singing in public too.
How you were treated: it depended on your race and class and their race and class.
Highclass/low cass: High class could do a lot. They had money and tended to own the land and people and even when they didn't own people, they still had money. They were given a ot more respect and could shoo lower class people out of the way.
If you want anything else, you'll just have to narrow it down.
