Hi, I have found a couple of things you may or may not have.
Robert Walker born July-Sept 1882.married July-Sept 1919 William Patrick born Apr-June 1884 Catherine Elizabeth born July-Sept 1885 George Alexander born July-Sept 1887 Edmund Luke born July-Sept 1889 Arthur John born Apr-June 1891.married Oct-Dec 1911 in Dundalk,co Louth and died Oct-Dec 1914 in Naas,co Kildare * all children of Walker & Mary
William's mother Mary Jane(Bond)Cooney died July-Sept 1923 I cannot find a death for the father
Walker and Mary married July-Sept 1881 Rathdown dist,co Dublin
I found 1 births that may be Mary's:
5 Dec 1854 SS.Michael & John,Dublin Mary Bond parents:James Bond/Mary Ann - sponsors:Patrick Dunne/Ellen Fleme *if you go onto the website irishgenealoigy.ie the records for Dublin both protestant and catholic are on there.Funny enough none of the births of Walker and Mary's children appear to be listed.
I looked at birth records for William's father Walker but I couldn't find anything but I wonder was he actually Church of Ireland or was he Catholic and raised his children C of I as it was his wife's religion.Secondly was he possibly born William Walker Cooney instead of Walker William? I hope this may help,Kim
