I have a Jonathan Briggs (1757-1837), born in East Greenwich, RI; served 6 years in the Revoultionary War, married Abigail Greene of Coventry, RI; And became a farmer in Coventry, RI. They had the following children: Giles (my line), Wanton, Olney, Polly, Niobe, and Hulda. I have been told that my line of the Briggs family arrived in the US in the 1600's, but this is as far back as I can go. I am somewhat suspicious that this John is the descendant of the John who sailed with Capt. John Greene for Warwick, RI and settled in Kingstown, RI in 1671, but I am not certain. Maybe we can help each other.
