Formerly a Christian name in the Highlands, in the Macdonald family, and first recorded as Giolla-Adhamhnain, the name of the father of Somerled of the Isles.

Gilleownan Makneill in 1427 received from Alexander, lord of the Isles, a charter of the isle of Barra and the lands of Boisdale in South Uist.

Gillawnane McCrouder in Comrie was one of the witnesses to a charter to John de Cumre in 1447 (RMS., 11 640). In 1495 there is also mention of a Gilleownan Macpheill, grandson of Gilleownan.
