Searching for people researching the surname BROWN in Lambton County. Charlotte Brown was the wife of Charteris Montgomery, married in 1850- they settled in Lambton in 1853. Charlotte's parents were William and Charlotte Bateman Brown, I dont know whether they ever came to Lambton- last known locale for them was Toronto c 1850.
Charlotte had brothers William and Henry who did settle in Lambton. Henry was unmarried and died in 1907, age 84. William had a wife, Jane, and children Richard (b. 1855) Charlotte (b. 1858) William (b. 1859) and Henry (b. 1861)
The Browns came to Canada from County Down, Ulster, according to Charlotte Brown Montgomery's entry in Beers' Biographical Dictionary of Lambton County, 1905. Thanks!
