I don't profess to be an expert on Irish pet forms, but I consulted a couple of friends who are well-educated/well-read Irish nationals re the usage of these nicknames in either Eire or Ulster.
Neither considered them "Irish" nicknames; they both said "English" sounded right. One also commented on the archaic nature of "
Addie", and speculated that the last person to bear that nickname probably went down on the "Lusitania".
This seems to be a question of some importance to you. Are you doing genealogical research on persons with these names?
