McGowan
McGowan /məˈɡaʊən/ is an Irish and Scottish surname. It is an anglicisation of the Irish Mac Gabhann and Scottish Mac Gobhann, both of which mean 'son of (the) smith'. Belonging to the Uí Echach Cobo, located in modern-day western County Down in Ulster, they were of the same stock as the McGuinness clan.
