Sweeney Vad efternamn betyder
Irish and Scottish: shortened form of McSweeney from Gaelic Mac Suibhne ‘son of Suibhne’ a personal name meaning ‘pleasant’. Loss of initial Mac in this surname seems to have been encouraged by the Irish variant Ó Suibhne. For the Scottish form Mac Shuibhne with loss of the final syllable and lenition of the personal name after Mac compare McSween and McQueen. Americanized form of French Choiniere. Americanized form of French Chouinard. Compare Swenor.
