Harmon
An Irish surname of Wicklow. In the 2010 US census it was carried by 74,737 people, the 438th most common surname in the country.
Harmon is the anglicised form of three distinct Irish names. Some you can hear in the English name; others look and sound nothing like it, and were simply swapped for it.
Hearman, son of Hereman (a Teutonic personal name)
Mac Giolla Deacair, son of Giolla deacair (hard youth). This family stood in Co. Roscommon.
Ó Hargadáin
Where the name comes from
Hearman is son of Hereman, a Teutonic personal name, and the surname came into Ireland in the 13th or early 14th century. Harman, Harmon, Hardman and Herdman are all the one word.
Mac Giolla Deacair, son of the hard youth, was peculiar to Co. Roscommon in the 16th century and reaches Harman by a different road. And Ó hArgadáin, descendant of the little silver one, from airgead, silver and so white or shining, is a Connacht surname now often but incorrectly anglicised Hardiman and Harman.
