2. Donald RUMSEY of Cortland NY had the family Bible in 1974

The info on John 3h - John RUMSEY b 1726, d. 1796 - married Ester JONES, came from David, whose line is from John and Ester. He said his records go back to around 1400, and the name reportedly comes from Romsie Abby in Romsey, England. He said that reportedly 3 sons came to America around 1600. One went south, one to Fairfield, CT, and one went back to England.

The line on Simon [1b above] - John, found on a Rumsey forum, is directly descended from Simon RUMSEY, NY d. 1798?

Greg Walter, found on forum May 4, 2000, said "there is a wonderfully large monument in the town square of Berkeley Spring, West Virginia, honoring the work of James Rumsey. If someone could send me a photo and data, I could put it up on a web page.

I will update this page when more information is available on this line.

Email and contact information on the two persons whose line I've started, above, are not listed because I have not asked for permission to do so.

I heard from a John Rumsey who is descended directly from Simon Rumsey, that the name has other possible spellings:
1. Walter de Romesay b. 1158/9, married Jeanette
2. Sir Walter de Romeseigh
