MULVENNA, McILVENNA (and other variants) are Irish surnames once found more or less exclusively around the Glenarm area of Co. Antrim. There are now MULVENNAs and McILVENNAs living in many places around the world, but as the name is relatively uncommon, MULVENNAs and McILVENNAs usually find that their surname is unique in their own area.

This group aims to facilitate communication between the MULVENNA/McILVENNA diaspora, encouraging gatherings and the sharing of family history.
