Look for them at the LeRoy Historical Society, 23 East Main St., in the old house in front of the Jell-O Museum (which is around the back). The two work together and visitors to the Jell-O Museum are actually supporting the work of the Historical Society, including the LeRoy House, originally the tiny home of land agent Jacob LeRoy but later expanded to be large enough to hold the first college for women in the U.S., Ingham University. It ran from the 1830s to the 1890s and expanded across Main St. and part of the property is now the Woodward Memorial Library. If you have a female ancestor who was noted at the time for being well-educated, particularly in the arts, look for her in LeRoy, NY.
Tucked away in a corner of LeRoy House (below) was a framed collection of "head shots" labeled something like "Class of 1880." Another item was a bookcase with shelves of plain gray-bound books labeled "lineage books." Who knows, maybe it was someone's records of livestock pedigrees, but the guide thought they had been donated by a group, maybe the DAR, making them human pedigrees. The Society does have a collection of records and will do genealogical research for you, so do contact them or better yet support them with a membership, just $25.00.
