Just a smattering of the places I've found:
British Women's Novels: A Reading List, 1775-1818
Regency Style Year-by-Year
Women & Power in Alta California
Early Modern Woman Database
Spanish Surname Practices
California Wildflower Index
A few minutes later: [wheezes from laughter] Death Rode a Pinto Pony (scroll down a wee bit)
And more later: bought this CD. I've been to a few Alta California dances, complete with period dress, and had a blast. Discovering there was a CD of the music was awesome!
