I can see births to 1871 now - perhaps John and Catherine’s children with mother Lally/Lully
There are these:
1868, John Lahey, mother Currigan
1869, Thomas Lahy, mother Gordon
1870. Mary Lahey - mother Gordan
Could these be the same family?
Then there is a Patrick and Margaret Leahy with their son John, 2 yrs.
