I'm looking for information on the family of William H. and Nettie P. CAMPBELL. According to the 1900 census, he was born in Aug. 1867 in PA; Nettie was born in 1879 in OH. Does anyone know when and where they moved to after 1900? They are not in the 1910 census, although Nettie is buried in the Westminster Cemetery; she died abt. 1911. Thank you. Kathy Campbell
