Thanks for that input Lord Vader, it's very very interesting.
I've made a copy which I will print off and study at leisure to get my head around matters.
Of course my/our research was long before Ancestry's Essex Parish Register Index (EPRI) came into being and really wasn't making much headway. Then after further research and lots of discussions on RootsChat and other means plus the message from the Reverend Mill's son, I came round to the theory of the Suffolk to Thaxted and then to Takeley etc line.
My Fewell line starts off with Sophia Fuel (Tuel on the EPRI

) who married into my Searles, her parents were definitely William and Margaret (nee Twinn) Fewell/Fuel.
I have recorded William and Thomas sons of Thomas and Elizabeth Fewell baptised 27 Apr 1740 at Takeley. Thomas Fewell married Elisabeth Judd 26 Jul 1735 at Takeley.
Also a William Fewell who married Elizabeth Green 7 Dec 1761 at Takeley.
Not sure if it's noted on this topic so as I'm running out of time I'll note it here, the Rev Mills considered that the Philip Fuell who married Ann Judd was the Philip son of John Fuell/Fewell and Elizabeth Green baptised 6 Jun 1714 at Little Canfield. John and Elizabeth married 3 Jun 1707 at Gt Dunmow by licence.
Looks like I have work to do.
Regards.
