The town historian was certain that a house still standing belonged to the Mann family. This house is at 303 South Main in Mannsville. The house has undergone a lot of renovation and additions, and even partially burned in 1887. I contacted the owner of the house. He has traced the house back to about 1848. He said he would look up old deed and title information and forward it my way. The current owner's family has owned it since 1949. He mentioned two curious features of the house; that it has some hidden large cubbyholes behind the stairs, and that there was once a large water collecting cistern on the roof.

I also was able to confirm where John Preston Mann's mother, Julia Doolittle Mann, lived with her son George and daughter in law Sophia in Watertown. They all lived at 32 Massey Street. George taught music at what was called, The Jefferson County Institute.
