I am looking for more information on the family of Elizabeth Ferguson, my second great grandmother. My family history shows that she was born Feb 10, 1813. She was married to Thomas Read (Reed) of Saratoga County on Dec 30, 1830 in Chautauqua County. They resided in Poland, Chautauqua, NY in 1840 and 1850 (she is listed as "Clara" on that 1850 record). After Thomas' death in 1863, she moved with her sons to Illinois (listed as "Eliza" on an 1870 census). I am looking for information on the names of her parents. I also don't know her birthplace.
