John Rawson Walker was a Regency/Victorian landscape artist. I'm trying (and failing!) to find out his family background and failing. In particular I'm trying to pin down where the Rawson part of his name comes from. It's fair to assume its a family name as his children all had it too. But I can't find any baptism for him.
Can anyone help?
Facts as far as I can tell:
b Nottingham around 1795-6ish
Shown on the electoral registers in Nottingham in the 1820s
Married Elizabeth Hoare in Derby in 1829 (though a marriage licence is listed as being in the Staffordshire collection on FindMyPast - I don't have a FindMyPast sub atm)
Children, all with surname Walker:
Albert b 1830 London
Isabel Rawson and Florence Rawson both b 1831 Derby;
Bernard Hoare Rawson bap 1834 Derby;
Herman Rawson b 1835 Leamington Spa (died 1837);
Blanche Anne Rawson 1837 Warwickshire
Dora Rawson b 1838 Leamington.
Lived in London in the 1840s-50s then back to the west midlands.
I've found most of the above family members in most of the censuses and the only extra clue is in 1861 when Isabell was staying with her uncle and aunt, Thomas and Mary Ann Knight in Nottingham. Thomas Knight m Mary Ann Walker in St Mary, Nottingham in 1827 so Mary Ann was probably John Rawson Walker's sister. Her dob across the censuses was 1791 - 1796 and pob St Mary's, Nottingham.
My Nottingham FHS disc has no Mary Ann Walker baptisms at St Mary's in the relevant timescale and no John Rawson Walker baptisms anywhere at all. The only Walker-Rawson marriage prior to this gives no baptisms to that couple at all.
Can anyone find anything else or make any more suggestions?
