My husband's great-great grandfather John Fitzhugh was believed to have come from Northamptonshire. He married Harriet Wyvill (from Mansfield) in St. Pancras, Nottingham and they and five children came to America between 1841 and 1851. According to old family letters, John's cousin Stephen Knight lived in Northamptonshire. I haven't been able to discover who John's parents were or where they lived. The June 1841 census showed that he was not born in Nottinghamshire as were his wife and children. Also, he was listed as a tailor. And according to letters, John had no sisters and his mother died shortly after he was married.
