It would be impossible to distinguish the numerous Ryan Families without nicknames. Only very rarely are nicknames resented and are the ordinary names of the people.
They seem to have been adopted in various ways
(1) from father's Christian name i.e.
Ryan Rodger
Ryan Rody
Ryan Billy
Ryan Éamonn Donnchadh
Ryan Andy
Ryan Davy
Ryan Denny
Ryan Joe
Ryan Lar
Ryan Tom
Ryan Ned
Ryan Pat
Sometimes these get a turn such as Lar's Bill, Ned's Tom, Pat's Paddy, Davy's Tom, Mick's Rodger or so on
