I do not have Lizzie (Elizabeth M.) Russell's parents names, however, from census records, her father was born in New York and her mother was born in Pennsylvania. My record shows her as being born in Des Moines, Polk Co., IA, on Oct. 26, 1847. Have you tried the 1850 censu record for that area. Her son, Lloyd Brittell married a Grace Russell. Probably a distant cousin.
