The Newell family are a recent connection, following the purchase of the CFHS "Ely St Mary's
Parish Registers 1599 - 1881" data cd.
I had known of my Newell connection for some time since the late Pam McClymont of the Cross One Name Study pointed me in the right direction of her extensive research. After a bit of checking up on pieces of her research against the records, I was able to see that she was correct and that the Newell family and their associated branches were amongst the data on the cd.
The earliest date that I have for the Newell family is the 7th October 1794 when my 6x Gt. Grandfather, Francis Newell married Mary Haylock at Ely St. Mary's church, Cambridge. I have managed to track five children from this family although closer inspection of the data cd may provide more children (as well as, in theory, their deaths).
