Hello,
Had a look on 1841 and loads of possibles for John Wheeldon. Using dob 1800 + or - 10 years (

) came up with 13 John's living in Derbyshire, none showing Ticknell.
(Couldn't be that easy, could it??)

It might come down to John's occupation as that's the only thing that varies. Also, not knowing the area doesn't help, but can anyone spot anything in the following?:
Parish born Occupation
Bakewell 1796 Ag Lab
Dalbury and Lees 1805 Shoe Maker
Edlaston 1796 Ag Lab
Hognaston 1801 Blacksmith
Kniveton 1801 Blacksmith
Ockbrook 1801 Ag Lab
All Saints 1806 Wheelwright
Youlgreave 1794 Lead Miner
Etwall 1791 Farmer
St Alkmund 1791 Cotton Spinner (?)
Ashbourne 1811 Ag Lab
Darley 1811 Flax Dresser
Duffield 1811 Joiner (?)
Any help??
Sally
