Although I have subscriptions to both Ancestry and FindMyPast, I am having trouble locating a pre-1837 marriage in Dorset.
Thomas Tizzard, said to be from Wareham (consistent through Census records) married Sarah

said to be from Wimbourne. 1841 census has them with 3 children - Elenor aged 6, John aged 4, and Frank aged 1. Frank, I believe was registered in 1840 as Francis with mmn = Eaton, as are subsequent children.
I believe that Thomas was born circa 1803 and Sarah circa 1811. Those years being consistent with census entries.
Any help would be gratefully received.
