I seem to have lost a message in the system somewhere so I will post it again,
Thanks everyone, but it would seem that I didn't make myself clear, no doubt family history brain addle has taken over. What I am actually trying to ascertain is which John Rolfe married Mary Hart, was it the son of William and Ann or was it the son of Richard and Ellen. I have the details of these two, I also have the marriage of John and Mary at All Saints Fulbourn Cambridgeshire in 1799 where both parties are described as single, but no parents listed. In 1820 there is a wedding at Fulbourn between Mary Rolfe (widow) and John Littlechild (widower) which might suggest that John died but in the 1951 Census mary is listed as Mary Rolfe widow and shown living with her son Henry, in Poor Well. If anyone has access to the Fulbourn 1841 census could they please try looking for Mary as both Rolfe and Littlechild, this may help to see if John did die and that the Littlechild Mary is another Mary Rolfe, there seems to be lots of Rolfes in Fulbourn.
Thanks again
