Maggie, have you seen the Earls Colne project website?
http://linux02.lib.cam.ac.uk/earlscolne/
They've indexed every person mentioned in any doc relating to Earls Colne since the year dot, including parish records. Some of my OH's family are from there and I managed to find quite a bit about them.
Edited to add - h'mm, I've checked and can't see any Lewseys listed at all. How sure are you he was born in Earls Colne?
