Haimo, also spelled Hamo, Heimo, Hamon, Haim, Haym, Heym, Aymo, Aimo, etc., is a masculine given name of Germanic origin. The Old French forms are Haimon, Aymon, Aimon, Aymes. It is a hypocoristic form of various Germanic names beginning with the radical haim-, meaning "home".
Haimo is the origin of a wide range of surnames, including English surnames like Hame, Haim, Haime, Haimes, Hains, Haines, Hayns, Haynes, Hammon, Hammond, and Fitzhamon. The Old French form Haimon was then combined with the diminutive suffix -et, giving the pet-name Hamunet, which in turn gave rise to the English name Hamnett and its variants.
