Pigeon
Pigeon—This name is the anglicised form of both a Scottish and Irish sept name. The Scottish name was assumed by a branch of the McCalman sept (Mac Calmáin); the name in Gaelic being Mac Coluim.
In the districts about Carrickmacross, Co. Monaghan, the M'Guigans, in may cases, have assumed the name of Pigeon (Mac Guaigín).
