My grandfather Robert William Cobbe b.1979 Kilkenny D. 1968 Dublin (rest of family/parents Athy).
I have an old text book of his with an entry Henry G Chaloner died January 1965 entered under Sept 16 (possibly his bday).
The story is that there was some connection with Charles Cobbe -Newbridge Hse but I have never been aqble to trace it. You state you have links re Cobbe Chaloner etc. I know it is a long shot but is the above Chaloner in your data or are you aware of any connection? Kind regards Mervyn Johnson
