Jane Duke 64
Lisa Duke 20
William Duke 62
-------------------
1881 says

John Cain 19
Jane Duke 60 widow

---------------------
problem jane is age 64 in 1871 and age 60 1881, i cant seem to find jane in 1821 for marown and i cant find a buriel for william duke in braddan,
I think this john henry is going to be my great
grandfather,
In 1891 census it sees john henry with the family
Elizabeth Bryan 62
Timothy Bryan 65
John Cain 27 lodger
Stanley Dougherty 30
John Faragher 70
Henry Watterson 73
---------- elizabeth bryan could be the daughter of william and jane duke,
Jane duke herself could be Jane cain befor she married william Duke, question is also , can i be 100% right, -like a fw people i find i cannot give up trying to find these family members and i do go to museum and bmd etc, they just dont want to come to me, john henry cain had a set of parents befor he went to dukes or what ever ,
