Hi, Just came across your message looking for John Ackerman of NY who died in 1833. My grandfather, John Douglas Ackerman was born in 1826 in Plymouth MA and had 1 sister (?name) and brothers- Walter Samuel, Charles Holmes, James Baxter, William Edward, and possibly Abner. Their father was a John Ackerman who was from NY and married a Elizabeth Douglas from Cambridge MA. We believe the father John died in the 1830's sometime. Wonder if there is a connection here?
