Origin
Meaning and origin of Mcmanemy
The surname MCMANEMY is of Irish origin, originating in the late 16th or early 17th century. It is derived from the Gaelic personal name "Mathghamhain," which means "bear" or "descendant of the bear." This personal name was later anglicized to McMananey, McMenemy, and eventually MCMANEMY.
The earliest recorded instances of the MCMANEMY surname can be found in various Irish records from the 17th and 18th centuries. One notable example is the Ulster Plantation Baronies of 1611, where the name McMananey appears in the County Armagh region.
In the 19th century, several individuals bearing the MCMANEMY surname gained prominence. One such individual was Patrick MCMANEMY (1807-1888), a noted Irish politician and Member of Parliament for County Leitrim from 1857 to 1868.
Another notable figure was John MCMANEMY (1820-1895), a prominent Irish-American businessman and philanthropist who founded the MCMANEMY Textile Company in Philadelphia, Pennsylvania.
In the early 20th century, James MCMANEMY (1875-1942) was a respected Irish-American author and journalist, best known for his works on Irish history and culture.
The MCMANEMY surname can also be traced back to several notable places in Ireland, such as the townlands of Ballymacmanemy in County Antrim and Kilmacmanemy in County Fermanagh. These place names likely derived from the surname itself, indicating the presence of MCMANEMY families in those areas.
Other notable individuals with the MCMANEMY surname include Michael MCMANEMY (1900-1976), an Irish-American labor leader and politician who served as a member of the New York State Assembly, and Margaret MCMANEMY (1919-2001), an acclaimed Irish writer and poet who published several collections of poetry and short stories.
It's important to note that while the MCMANEMY surname has its roots in Ireland, it has since spread across the globe, with descendants bearing the name in various countries, including the United States, Canada, and Australia.

The Census Bureau groups responses into six broad categories: White, Black or African American, Hispanic or Latino, Asian and Pacific Islander, American Indian and Alaska Native, and Two or More Races. When a category has too few respondents for a given surname, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.
Percentages are shown for every Census year so the breakdown stays comparable over time. When the source file also includes raw headcounts, Name Census shows those alongside the percentages in the legend.
Keep in mind that these are self-reported numbers. A person's surname does not determine their race or ethnicity, and the distribution you see here reflects the specific population who happened to carry the Mcmanemy surname at the time of the 2020 Census, not any inherent property of the name itself.
