The 1871 census I was looking at was in the Parish of Michael

On the census, they are on page 4 and living:

20 Ballagowne (think this is the spelling)

All residents born in Michael

John Kelly Head 64 | Not sure on occupation
Jane Do Wife 50
John Do Son 25 | Mariner at fishing
Jane Do Daughter 16 | Housemaid
Wm Do Son 13 | Scholar
Robert Do Son 10 | Do
Elizabeth Do Daughter 8 | Do

All children unmarried

On same page of census, there is also a John Kelly above married to a Elizabeth Kelly (next door)

19 Ballagowne

John Kelly | Head | 25 | Mariner at fishing | born Michael

Elizabeth Kelly | Wife | 21 | Born Patrick

I may have spelt "Ballagowne" incorrectly, but that is what it looks like on the census - 18, 19, 20 and 21

Let me know if you need any further details
