Hi Julie & Sue, My friend has confirmed the marriage, William Fewell married Margaret Twin (as spelt, no double n) 3 May 1768 at Felsted, in the presence of Edward Connell & Thos Green. He found no children of theirs in Felsted, he also checked a Gt Waltham fische and confirms the children we already have. The Mary Ann you mentioned is only shown as Mary in the register fische but the date is correct. Another entry in the Gt Waltham Baptism Register fische read "........... of William & Margaret Fewell baptised Jan 20 1770". My friend wrote that the name part of the entry was not illegible, or crossed out, it was just blank. It begs the question was this a still-born child? I wonder whether the original Gt Waltham register could contain an explanatory note somewhere which hasn't been put on the fische? So apart from the unnamed 1770 entry in Gt Waltham there are no baptisms in Felsted & Gt Waltham between 1768 & 1776 , so where were William & Margaret between 1770 & 1776?. Bit of a mystery there at the moment, unless of course they abstained for a while.
