I'm a descendant of Mary Ann Margie Grant, b. 29 Jul 1808 at Marietta, Ohio (according to her obituary). She was the second wife of William White, m. 1825 in Fearing, Ohio. Mary had at least 10 children. During their marriage, they took a wagon train to California. William returned to Ohio and died there. Mary stayed in California and died there 23 Feb 1882.
Can't find anything about her or her family.
