The townland of Drumennis is in the parish of Kildarton in Armagh County. It is labelled number 8 on the map.
Paterson (Armachiana, Vol. 16) notes:
Drumennis. 'The ridge of the holm or island'. Inis gives name to a vast number of places but in every individual case whether the word means holm or island must be determined by physical configuration of the place. It occurs in another form in Ennisclare, the middle island or holm, a townland on the main road to Keady. (p.23)
Drum (Druim) [meaning 'ridge'] is one of the most common names and figures as a prefix to about 2,400 places besides an equal number in which it is combined. (p.21)
