Mathieson, Matheson - Anglicised Surnames in Ireland

Padraig Mac Giolla-Domhnaigh
1923

Mathieson, Matheson—These two names are the anglicised forms of the Scottish clan name Mac Mhathan. Its earlier form was Mac Mathghamhna, similar to the Irish form of M'Mahon. Some of the clan still retain a lesser anglicised form in McMathan. Matthewson is another form assumed.
