Ralph Smith came to America in 1633 from Hingham England.
He was one of the original Settlers of Hingham Massachusetts. There are hundreds of us that are descended, and you still maybe one of us, but your Reuben was not Ralphs son, and your dates are wrong. I would need more information to tell you more. There is data that says Ralph had two brothers, and I am in contact with their descendents as well. Good luck. Franklin
