Hi Royd,
Following on from Allisont's clue, I have found this entry in the Toot Baldon PRs (ex OFHS);
Marriage;
22-5-1861 WEST, Thomas Clarke, fa, bach, Policeman, Tottenham son of Thomas Clarke, Labr to
POOLE, Maria, fa, sp, Toot Baldon, dau of William, Labr, by Banns
wits; William Gooding, Emma Clarke.
There is no entry for Maria Poole's baptism in Toot Baldon PRs
Hope this may be of some assistance.
Now just to add, in the Marsh Baldon PRs (ex OFHS) I have just found this baptism;
10-2-1839 WEST, Thomas Clarke, son of Martha, Single woman, Nuneham Courtenay.
This may confuse the issue.
Alan
