He is named after his maternal grandfather Thomas J. O'Malley (Tomás Seosamh Ó Máille), who was a native Irish speaker who imigrated to New Jersey from Galway. He is also nephew of Irish-American aerospace engineer T.J. O'Malley.
Born Thomas Ihde, he was given the Irish version of his surname, Tomás Ó h-Íde, by his first Irish language teacher John Egan (Seán Mac Aogáin) of Curramór, Co. Galway. He legally Gaelicized his name in 1989 at the Central Office of the Four Courts while living in Ireland.
The German surname Ihde is of Viking (Old Norse) origin. It is a variant of the surname Ide from the Old Norse for "zealous, hard working". Note that this surname does not appear to be related to the English surname Hyde which has its origin in the old British measurement of land, a "hide".
