KING, William b. 1809 Ottery St. Mary

[Chattykathy]

Looking for information on William KING b. 1809 in Ottery St. Mary.  Birth record, Parents names, marriage records, etc.

Note, William is found in 1851 and 1881 living @ 6 Sand Hill, Middle Claydon, Buck.
Wife listed as "Sarah" in 1851 and  "Prudence"  in 1881  either b. 1806/1807 Burton Warwickshire or Burton Dorset.  Thinking this is the same person --  Prudence Sarah/Sarah Prudence??
Her Maiden name unknown.
William had 5 children but all born in Steeple Claydon.

There is conflict between William's  birth location in the 2 census reports but fairly certain they are same person as his birth date (1809) is consistent and in 1881 youngest dau Maria b. 1847 living with him/Prudence along with her children.

Thanks in advance for any assistance offered!
