Gahan (surname) Irish language "Mac Gaoithín", meaning "son of "Gaoithín"", although the more common Anglicised form of this Gaelic name is "McGeehan" in Ulster. Gahan (surname) Gahan (and its variant Gahame) is a surname with several different origins. One origin of the surname is from a reduced form of "McGahan", which is in turn an Anglicised form of the Irish language "Mac Eacháin", meaning "son of "Eachán"". Another origin of the name, in Leinster, is from a reduced form of the Irish language "Ó Gaoithin", meaning "descendant of "Gaoithín"". The personal name "Gaoithín" is a diminutive of "gaoth", meaning "wise", or "wind".
McLaughlin (surname) and M(a)cLoughlin are rarely English forms of the surname "ó/ní Lachtna", a phonetic corruption of the much more common "Loughney" or "M(a)cLoughney". Unlike Irish surnames that have only one Gaelic source for their English form, it is not possible to tell by the spelling "McLaughlin" and other English spellings whether the person bearing the name is descended from the "Mac/Nic Lochlainn" family, the "Ó/Ní M(h)ǽilsheáchlainn" family, or the "Ó/Ní Lachtna" family.
