Hi Elsie, There is a Gibson family that lived in Antrim, N.H. in the mid 1800's. My ancestor John Curtis; son of Jacob Curtis of Amherst and Mt. Vernon married Mildred Gibson and they lived in Windsor, N.H. which is adjacent to Antrim and Hillsboro. I don't know if there is a relationship but the name is common in those towns. Bill Curtis; Newton, N.H.
