I've just added sources to Rice's profile and left the following comment
It is clear that Rice was born 1630 ish or earlier from the fact that he was married in 1651. Even though there is no firm date for the marriage of Solomon and his wife, Rice was born some 13 years prior to their other children and in the settlement of Solomon's estate, Samuel was called the eldest son. He needs to be disconnected. Objections? --- I will follow up in a few days, to give the objectors a chance to object.
Also, we don't have a clue where Rice was born, his profile now reflects that. Thank you Scott.
