I think you really need to find all the Childrens Christenings to establish the Parents names.
It is possible that Henry may have been Married twice.
It may be a blended Family.
1851 they have Children;
ROBERT 1818
MARGARET 1822
JOHN 1823
HENRY 1831
All born Egremont
+ Grandsons, HENRY 1848, ROBERT 1850, born St John
If I am correct this is the 1841 Census;
HO107/156/21/St John Beckermet
Henry KITCHEN, 50, Canvas Weaver
Martha, 50
Henry, 10
John, 14
Issabella, 8
Robert, 20, Canvas Weaver
All born in County
Ages rounded of course in 1841
Ok, where is Margaret in 1841?
Isabella may have Married by 1851 Census or moved away.
