Hi There.
This is what I could find on the Tucker family in 1841.
Living in Witheridge, Devon.
John Tucker. Age. 30. Labourer.
Ann Tucker. Wife. Age. 30.
Charlotte Age. 10
John. Age. 7.
Ann. Age. 4.
Susanna Age. 10 months.
I hope it helps. In 1851 the family are living at Billhole Cottages, Thelbridge, Crediton, Devon.
I have the 1851 census if you need that information.
