Joseph Williams born c1750 woodham ferrers area?

[nannyj]

I have Joseph married to Sarah (don't know surname or date or place of marriage) having children from 1770 in woodham ferrers until 1783 when Sarah dies. (Richard 1770, Martha 1773 - my 5th great grandmother, who married Joseph scales in woodham ferrers 1789 and had children in benfleet, dying in 1815 in bowers Gifford - and Samuel 1783).
Looking for their marriage (and therefore her maiden name) and his and her birth.

P.S. I have SEAX but can't see it? If anyone else can see it, I can go from there 😊
