He may have lived in Taunton when young and that is why on Census he had that as POB.
He was Baptised there;

ANN Kingdon, same Church, 29 March 1829
Parents JOHN/SARAH
Abode Eastreach
Fathers Occp Printer
I would say that the entry may have been hard to transcribe for Ann and it is East Street and Fathers Occp Painter, not Printer,
For some reason the links that CaroleW gave wont open for me.
This is what I found, so not sure if its the same as CaroleW gave ;
Marriage;
28 June 1823, St John, Wellington, Somerset
John KINGDON, Widower, to Sarah WILLIAMS
(FreeREG)
Possible Burial;
SARAH Kingdon,
11 November 1846
St. Augustine'S, Bristol, Gloucester, England
Age 60 (birth c 1786)

There is also a JOHN Kingdon Death Reg 1850, Bristol, Gloucestershire.
But no age given so hard to confirm if the correct one.
