Melissa, do you happen to have the name of David Jefts' spouse. The History of Mason, NH show that there were 2 David Jefts who got married in 1803 and 1804. The first David married Edee Barrett on April 10, 1803. The second David Jefts married Abigail Barrett on April 5, 1804. Curiously the second David was known as David Jefts the 2nd, in both the town records and the census. One stayed in Mason and the other eventually moved to Vermont.
