Hello Frances.
The Robert Henry Corkill, son of Robert and Elizabeth Christian was christened in Malew. Both his parents shown living in Malew.
This Robert is with his grandmother on 1861 and 1871, and is shown as born Malew. I think he is a lodger with the Quayle family in Conchan shown born Onchan.
Susan's Robert Henry on the 1911 census shows he was born Castletown.
Have we the correct one ? There are quite a few Robert Corkill's born around that time.
I think I found the other Robert Corkhill who was with parents John and Mary at Castleward on 1861 and 1871 , immigrating to the US in 1878 and dying in 1901 aged 45.
Another of this era was in Barrow In Furness in 1881 with wife Eleanor Killey ( Marr Dec Qtr 1880 B-I-F) , aged 24 shows born Ballaugh as was Eleanor.
I still think we have not yet joined Robert Henry Corkhill with Grandmother in 1871 to Susan's Robert Henry on the 1891 census in Toxteth Park.
