Grose Family Genealogy Forum
Believe she is the daughter of Samuel Grose, Jr., born abt. 1793, d. 1-11-1873. There are records of two marriages for Samuel, the first to Julia Nancy Jane Oliver on 9-7-1815. Two sons, John McDowell Grose, born ca 1817, and William O. Grose born ca 1819 are the children of that marriage.
Samuel is also shown as married to Mary Ann Oliver (no dates), and having the following children: Mary A. Oliver Grose, b. ca 1820, and Eliza Oliver Grose, (no dates), who married a McMillion. I believe there is something wrong with that research. Too many people named Oliver!
