I am searching for the parents of Harriet Marten, b. 1838, PA, and Anna Marten, b. 1845, PA. Harriet married Rev. William J. Trimble, probably in Ohio sometime in the 1860s. In the 1870 census the Trimbles are living in Ontwa Twp, Cass Co, MI (Anna is living with them). By 1880 Harriet has died, and William and family have moved to Chattanooga, TN.
