Thanks John, just shows you should always look at the original, not a brief description. That makes a lot of difference, and would explain why I haven't found any baptisms! Doesn't explain why I can't find the marriage though!
How about marriage in Potton on 3 May 1700 of Richard HEDING/HARDIN of Blunham, joiner to Sarah Day of Potton.
Baptisms then follow :-
6 Apr 1701 John, son of Richard & Sarah Arding
11 Nov 1705 Sarah, daughter of Richard & Sarah Harding, carpenter
3 Jul 1709 Richard or Joseph and Robert, sons of Richard & Sarah Arding/Hardin
Cheers John
