I have roughly estimated John's year of birth. Information on John as a son of Joshua & Rhoda came to me from Ian Feavearyear.
Fall River vital records list the death of a John Elsbree on 17 Jan 1844, at age 38. It says he was a manufacturer and died of consumption. I have made an assumption that it is this individual, because the age is about right, and also his wife and children are without him in the 1850 census.
See notes for John's (presumed) second wife, Fanny.
