Aodh Mac Cathmhaoil, O.F.M., (Latin: Hugo Cavellus; anglicised: Hugh MacCaghwell) (1571 – 22 September 1626), was an Irish Franciscan theologian and Archbishop of Armagh. He was known by Irish speakers at Louvain by the honorary name "Aodh Mac Aingil" ("Mac Aingil" is Irish for "Son of an Angel"), and it was under this title that he published the Irish work "Scáthán Shacramuinte na hAthridhe".
Aodh Mac Cathmhaoil was 55 when he passed away
it is not known when in 1571 he was born, so he could have not been 55, but 54
