Marriage of Edward Memlriy 3 May 1730 in Chaffcombe, Somerset to Sarah Farnett. Chaffcombe is only 6 miles away from Crewkerne, according to Google maps. And Cudworth and Crewkerne are only 4.7 miles according to this also. This looks like a likely marriage, as all of the places are very near each other, and a misspelling or mis-transcription of his surname.
These are the siblings of Edward, although none are born nearer to the 1730 marriage. They might be under a different variation or parish.
Esther 1744
Aaron 1743
*zoth 1739 (can't read)
It looks like Edward himself was baptised in Cudworth along with these children I happened to find. He was born 1709 to Aaron and Sarah Membry, which makes sense as he named his own child Aaron.
A Sarah Membrey, widow, buried 1759 Cudworth.
The site I have used is freereg.org. You'll probably be able to find quite a lot on there. Make sure to tick the variation box!
