Hello Mocam,
I'm having to look through every message on the One Name Interests as the subject rarely mentions the locaction. This is how I noticed that your ancestors were from Co. Cavan. Griffith's Valuation extracts for Cavan (1856-7) list two families from Kingscourt. The valuations are on John Hayes failteromhat.com website
Samuel Mark Campaign, Kingscourt, (Dunaree), Enniskeen. Cavan
Silvester Turne Campaign, Kingscourt, (Annagh), Enniskeen. Cavan
I think that the Mark and Turne were part of the Christian names although on the Valuation they are linked to Kingscourt rather than to the names section.
There were two other Campaign families in Ireland at the time of the Valuation.
Thomas Campaign, Ballynaclose, Enniskeen. Meath
James Campaign, Drumbrackan, Magheracloone. Monaghan
