Do you know if there was more than 1 couple Richard & Sarah in the parish? The day after Cicely's baptism, in October 1755, Alice, daughter of Richard & Sarah was also baptised. Were they twins?
1st baptism of a child of Richard & Sarah at Ormskirk seems to have been James, 1743. A Richard & Sarah Dutton had a son baptised at Rufford 1740. Burial of a Sarah, wife of Richard, 1764, Ormskirk. (LAN OPC).
If there was only 1 Richard & Sarah their marriage must have been 1743 or before (or 1740 or before if the couple at Rufford were same people). Both dates pre Hardwicke Marriage Act.
I couldn't see a baptism of Richard at Ormskirk, so he may have come from elsewhere.
