There is a Mary Hart 32 England, living two houses over with the Thomas Bremmer family.Not sure that this is YOUR Mary however, by her age in the 1860 census, it would support that.

As you can see, James is nowhere to be found around the family!Using various search strategies turned up nothing, even in subsequent census'.Do you have any other information on this elusive James?Did he marry and have children?Do you know whether he went by his middle name?If so, I might be able to locate him using that information.
