Wheelie not much help I'm afraid,but youv'e probably caught this going by,there was a Pat Whelan living at No 16 O'Brien Street Waterford,1910/11.They are 'in' with mine,but I have not chased them up.
That address was given me years ago by my old Mum,no trace of the folk's I wanted though !!
Keep on keeping on,Goggy
