Hi, Thank you so much for the information, yes they did marry. The ceremony took place on the 14th May 1826 at the parish church of Sixpenny Handley, Dorset. William was staying at Ebbesbourne at the time, so I assume that banns had to be read in both parishes.
There is of course no mention of his parents in the records, so I am stuck, it seems to have been quite a common name in the area at the time.
thanks again
Madeleine
