Just a thought tho...if the mother of Anastasia and Daniel was Anastasia Whelan and she died in 1905 I wonder why his wife would be listed as Eliza? Unless she was Anastasia Elizabeth or he divorced and remarried. . Wonder why they would ship Daniel off and keep the rest of the children.
Anyway I suppose doing this will always raise more questions than answers. There must be local records of employees of the railways in Wexford. I am going to try that route for John Doyle I think. May give some other clues.
