My apologies!
By 'they' I was meaning Nathan Gadsdon and his wife Sybella. Their daughter to whom I was referring, would be Ann M Gadsdon, born circa 1850 in Chelsea, MDX according to the 1861 census.
I can find no obvious marriage record for Nathan and Sybella, and no birth or baptism record for Ann M. Also, no trace of Ann M after her appearance on the 1861 census.
I will do my best to be more clear in future!
