Mulhussey

Mulhussey is a surname of Irish origin. It is generally understood to be an Anglicized form of the Gaelic surname Ó Maolchaocháin, meaning "descendant of Maolchaocháin." Maolchaocháin is a personal name comprised of maol, meaning "tonsured" or "devotee" (often referring to a follower of a religious figure), and caoch, meaning "blind." Therefore, the name could be interpreted as "devotee of the blind one" or "devotee of a person with impaired vision."

The surname Mulhussey, and its variations, are most commonly found in County Sligo and County Mayo in the west of Ireland. Over time, the name has been Anglicized in various ways, leading to different spellings, including Mulchuse, Mulhuse, Mulhousey, and others. Records of the name can be traced back several centuries in these regions. As with many Irish surnames, emigration from Ireland has resulted in the name being found in other parts of the world, particularly in the United States, Canada, and Australia.
