Marriage of John Croucher and Hannah Streat in the IGI on 15 October 1788 in Farnham, Surrey.
The same information is in the West Surrey Family History Society Surrey Marriage index, but spelling her surname Streate, and adding both were of this parish.
I assume his wife was Ann Streat, christened in Farnham on 19 December 1764, father Henry Streat.
