Gibel,
what a stroke of luck as I have just spent the morning researching Sarah Maria Cartwright/Fenton.
I established that John Speed married Sarah in 1858, but yesterday I received a copy of a birth certificate for Alma Speed (their daughter) which stated Sarah was formerly Fenton, although their marriage was registered under Cartwright and she appeared to be too young to have previously married. So it was back to the drawing board this morning.
I have now found out that she was the natural daughter of Mary Ann Cartwright who went on to marry John Fenton in 1847. I have located the Fentons in Bedlam Lane, Newark in the 1841-1871 census returns, Mary Ann and John's marriage in 1847, their deaths in 1873 and 1876 (respectively), their 10 children born between 1842 and 1861 and the four children of John and his first wife, Ann, between 1832 and 1836. Goodness! The family must have dominated the chimney sweeping market in Newark!
Now like you I arrived at the point of trying to establish the marriage for John and Ann and came across the John Fenton=Damaris Burill marriage as a likely candidate!. Wondering if Ann was perhaps a nickname for Damaris, I did a web search and up popped this thread.
Therefore I have just registered to RootsChat to send this message.
You obviously have a head start on me, so wondered if there was anything you would be willing to share with me. FYI: I always do my own research to verify any information received as I hate those who just take other people's research and simply post it without verification.
regards Dave
p.s. if I can work out how to do it, I will send you a PM.
