Sorry but there is not marriage of a Hugh Harley to Ann in Kensworth in 1795.
I've also checked neighbouring parishes of Eaton Bray, Caddington, Whipsnade, Luton, Totternhoe and Studham. The only Harley marriages in Kensworth around that time were:-
1) Thomas Harley to Sarah Hudson on 29th March 1794
2) John Hopkins to Elizabeth Harley on 3rd October 1794
3) Thomas to Susanna Ellingham on 17th March.
One of the Thomases is probably the Thomas son of Thomas & Ann who was baptised on 13th August 1769.
There is another Thomas Harley marriage on 27th October 1803 to Sarah Wilson.
I'd try extending the search to include Hartley.
