I know and I can't seem to find Sarah in 1851. 1851 census taken on 30 March 1851, and Samuel and Sarah were married in March quarter 1851

Some kind soul has added a postem to the FreeBMD entry, giving the place of marriage as St Mary, Cheadle but doesn't give the date

Venue confirmed from CheshireBMD. FindMyPast have Cheshire records, but nothing for Cheadle
