What I knew about her as of this morning was this: She was born in about 1841. On January 1, 1860, she married John Jackson in Kirkheaton, West Yorkshire. They had a son named Beaumont, who moved to Manitoba. Eventually Ann also moved to Manitoba (between 1911 and 1916, I think).
Today I discovered the site Beaumont Family History, which specifically says it studies the Beaumonts of Yorkshire! I was so excited! So, I sent them an email telling them what I knew about Ann Beaumont. Within a few hours I got an email back from Diana Beaumont, telling me that Ann lived in an area they hadn't covered in detail yet, but still giving me two census records, which give me the names of her parents, and 4 siblings. She also provided the exact dates of birth and baptism. I nearly fainted with joy.
So, here's what I know now: Ann was born on February 5, 1841, and baptised in Kirkheaton on May 16, 1842. Her parents were John Beaumont, a surgeon, and Mary (ooh, looks like I've got another brick wall to chip away at!). In the 1841 census, they lived in the household of Joshua and Ellenor Inman, on Stafford Hill (perhaps this street; check out that street view: beautiful!). Next door was a 60 year old John Beaumont, who could possibly be Ann's grandfather. Here's what the censuses contain:

This is so exciting! I'm not very good at working with UK records, but at the very least I can take this information to the library and search the Ancestry database, and hopefully find even more details.
I'm so grateful for the genealogy community! I only hope I can be this helpful on someone else's brick wall one of these days! :)
