George and Hannah did have a Hannah Abbott but she was born 9 June 1850 so that would not be the same Hannah and she married John Chandler. I only show George and Sarah Farnum having one child, Nehemiah born in 1667 so they certainly could have had a daughter Hannah. The time period is about right. I have a recod of a Hannah Abbot being married to James Ingalls but do not show her parents. James is the son of Henry Ingalls who I am also related to. It seems highly unlikely that George and Hannah Abbott would have two daughters by the same name when their Hannah born in 1850 lived to adulthood.
