Thank you everyone, your replies greatly appreciated.!!!!!!This is the mystery (which seems to puzzle you all also) and has bedeviled me for years,
the absent Charles Frederick Wilson B abt 1852 ish.
Where does my information come from ? It is thus.....
1861 census I have Margaret Mundy in Gorton, with Matthew Brien b 1840 son to head age 20 Ireland
(can`t find her as records are scant)Elizabeth Mundy daughter age 8 b Stockport 1853 (who wed Charles Frederick Wilson)
Joseph Mundy son age 1 B Gorton Lancs
THEN
I find on
1881 census Salford 30 Factory Lane.
Margaret Mundy Head Widow b Ireland.
Joseph Mundy son 21 dyer Salford (although it said b Gorton in 1861)
Clara Mundy Dau 17 spinner Salford
ELIZABETH (nee Mundy) Wilson MARRIED 28 cott spinner b1853 Stockport.
Marg Ellen Grand daugh to head 8 b1873 Salford
John William Wilson Grand son to head 6 b1875Salford
1891 Census Salford
Elizabeth (nee Mundy) age 38
WIDOW head Shopkeeper b1853 (Salford but 1861 said Stockport)
Sarah Jane Wilson " 8 dau b1883 Salford
John William Wilson " 16 Son Circular sawyer? b 1875 Salford
Joseph Mndy Brother " 32 Machine Maker b1859 Salford
THE MYSTERYI find no birth marriage or death for Charles Frederick Wilson b about C 1853?
Do not know place of BIRTH or DEATH.Death must have been between 1883 and 1891.
Why? because last child b1883 Sarah Jane (named a wilson, it could of course be presumptive as we know that although this child is named Wilson it may not be his child, but one assumes until proved wrong).
CFWilson is listed as a PLUMBER (maybe a journey man plumber so he was a mobile creature
) on my G G father`s marriage certificate in 1894 ( a John William Wilson b 1875). but CF Wilson was NOT listed as dead, in father slot.
As plumbers in those days dealt with LEAD pipes etc, madness may be an occurrence, so I wonder if Charles Frederick Wilson was in an asylum (eg he was thought of as dead by Elizabeth, wife and stated so on census

), and often the death was not recorded or the bodies were dumped in a mass grave after abuse.
JUST wondering if this was so, because I find no record of him...
