John Henry Crossman, born February 2, 1800, appears to be the son of Ebenezer Crossman and Polly Davis, although further research is needed to verify this connection. The Crossman Home Pages contain this information, and also many generations back from John Henry Crossman. The information provided on the following pages begins with John Henry Crossman and his wife, Martha Lamphere.
If you have any additions or corrections please let me know. I am also interested in any information on Martha Lamphere.
