Hi Jared nice to hear from you, as you have probably noticed there has been quite a few of us researching the Fuell/Fewell line.
The couple you mentioned, William Fewell and his wife Elizabeth Green, did come up on our Radar, like you I am of of the opinion that their son Philip married Ann Bird.
As you are probably aware myself and others are of the opinion that the Philip and Ann Fuell who baptised a daughter Millicent at Takeley in 1754, are Philip Fuell and his wife Ann Judd who married in 1736 at Takeley, several of us believe it is their son William Fuell baptised in 1737 at Takeley who married Margaret Twinn and is therefore our ancestor.
My line as it stands at the moment is Philip Fuell (c1711) & his wife Anne Judd
Their son William Fuel (1737 Takeley) he married Margaret Twin in 1768 at Felsted.
Sophia Fuel (1791 Gt Waltham) daughter of William and Margaret, she married Thomas Searles in 1809 at Gt Waltham
If you have evidence to the contrary of anything I've mentioned on this topic or disagree with the line of descent, I would like to hear of it, with several William Fuels/Fewells around and a couple of Philips floating around the area of HBO, Takeley etc it's not been an easy task sorting them out.
William Fuel and his wife Margaret Twin(n) also baptised a daughter Milly, she was baptised in1786 at Gt Waltham.
