Sperry is a name in Mormon History. They converted to being Mormons. Have you looked on the LDS website familysearch.com to see what is there on Sperrys? You also might look in the Family History Library Catalog to see what records are available for research on the name, and/or the location. Often there are books compiled on the surname, as well as local geographical areas. Pat I am looking for Lovejoys in the same areas.
