If they remained in Ireland you could look for their deaths.

........I wonder what happened to Mary & Patrick Kelly

Patrick Kelly (a stonemason) died in 1892 at Brewel. Daughter Kate was the informant.

See the 1901 census below.
Martin Kelly born 1877. Father Patrick Kelly (a stonemason) was the informant.

Hi

Looks like the Births of both ‘Murtagh’ and ‘Martin’ were registered on 17 Mar 1877.  See

They were born on 17 March 1877 (twins?), but registered on 7 April 1877.
