I have some information on the parents of benjamin Gifford. I think I have been in contact with you before. Benjamin's parents were William Gifford and Sarah Samson. I have the Samson line. On the Gifford side it is impossible to trace earlier than William as not enoughinfo is available. Best bet would be to check probate record in Bristol County for a William Gifford to see when he died and if an age is given. I think he died either in 1816 or about 1838. I think his widow died about 1849 in Fairhaven where her son Benjamin lived for a long time.
