I was looking to see whether there was a newspaper announcement of the marriage - didn't find one, but did find this:
Berkshire Chronicle 06 February 1864
Kingsclere Petty Sessions____William Richardson of Woodcott was ordered to pay 15s 6d costs, and one shilling per week, under the "incidental population act", to Mary Ann Alder, of the parish of Ashmansworth, spinster. Defendant, who had been paying 1s 6d a week to the girl since 28 September 1863, now got off the odd sixpence, it having come to the knowledge of the Bench, that Mary Ann had been indiscreet on a former occasion.
