Research Notes:

FM (vol. 3, pp. 98-99, footnote "k") states:

k The Sons of Osdealv, i. e. the Mac Costelloes. - According to the Annals of Kilronan, the island of Inish Cothrann was plundered this year by Gilbert Mac Gosdealv, and his English followers, and the sons of Gilchdreest Mac Carroon, vis., Gilla Croichefraich and Auliffe, who had the tribe of Muintir Maeltsinna with them. According to the Dublin copy of the Annals of Innisfallen, it was plundered by Gilbert de Nangle; and this is correct, for De Nangle was the original name of the Costelloes.

Woulfe (p. 397 s.n. Mac Oisdealb., Mac states:

'son of Oisdealb.' (Os-shaped, shaped like the god Os); a patronymic surname assumed by the family of Nangle. It is the earliest Anglo-Irish Mac-surname recorded in the Annals (A.D. 1193).
