1871 at Ellerslie Marown:-

Robert Cain 40 farm labr. Braddan
Margaret (Crowe) 38 Bride
John 16
William 14
Robert 7
Margaret 4
Emily 1

This John was christened John Henry 1855, I suspect he lost a few years by 1901. In 1881 the family were in 14 Hanover St. Douglas.

1901.
John Henry Cain 39 Labr at Gas Works
Edith A. 33
Lily (Lydia?) 11 christened Cowell.
Henry 7 christened Robert Henry Cain.

Does this fit?
