Had a look on familysearch and free reg for parents baptisms
William Cooper 15.2.1814 Rushmere s of William and Mary Ann Cooper.They had 2 other children curiously with her maiden name of Bryant added- James 4.3.1810 and Sussannh Briant 23.101.18o8,born 12th October a private baptism.
Married at Rushmere 4.1.1808.
Mary Ann Gorble ,all I can find for her is a baptism 11.3.1822 Lowestoft to Elizabeth Gorbell but that obvioulsy doesn't match with a mother Sarah which I also think she is on the 1861 census.Hopefully the marriage certificate will give you more.
