I don't have much on the Morgan side. My Gr Grandmother was Charlotte L Morgan, her father was Gideon B Morgan, mother was Mary Atkinson. They lived on Bingham Road in Marlboro, Ulster County. This is a 'stone's throw' into Ulster from Orange County, Town of Newburgh.The 1855 NY census has Gideon born in Sullivan County.He was born in 1825 died in 1891. Mary Atkinson was born in Orange County abt 1825 also. These dates would probably eliminate connection to your Sarah in 1859. There are other Morgans on Orange County that are likely older families.
