Hallo: As promised I looked up Blackmore again. The microfiche of the original registers gave very poor images which were too much for my eyes.
However there are splendid transcripts covering baptisms, marriages and burials for period 1602-1812 (ref: T/R 219/1).
There are indexes to the 3 sections of baptisms, marriages and burials but these were the only 2 indexed for WINLEY (or WENLY, WINDLEY etc):-
Baptism 17th Dec 1780 William WINLEY son of James and Sarah
Burial 14th March 1792 Charles WINLEY son of John
In case the index was faulty I also searched all baptisms for 1700-1760. No further finds
