Melanie: According to the Journal of the Cork Historical and Archaeological Society (July-September, 1915) the Hodnetts "had large possessions in Timoleague, Courtmacsherry and Cove. One of them took the name of Sherry (i.e. Geoffrey) instead of Hodnett . . ." From this came the surname Macsherry (not McSherry).
Macsherry, of course, means "son of Geoffrey). It seems that most of the Hodnett settlers in Ireland kept their original name.
