Sorry I should have said I have them on the 1911 census NOT 1901 ....senior moment!!
In the 1911 census they are living at 26 Montgomery St Carlow, they had three children:-
Eleanor Elizabeth Roche Connor b1907 Carlow
Eileen Bertha Connor b1909 Carlow
Rhona Parker Connor no dob shown on census form b Carlow.
I am over the water from you in Lancashire and may not have access to some of your Irish Data bases for marriage records.
Many thanks
