Origin
Meaning and origin of Carmoney
The surname CARMONEY is of Irish origin, tracing its roots back to the 16th century in County Monaghan. It is believed to have derived from the Gaelic phrase "Ceárta Mhuine," which translates to "the fertile plains" or "the rich meadows." This suggests that the name may have originated from a family or clan residing in a particularly fertile region of Ireland.
One of the earliest recorded instances of the name CARMONEY can be found in the Fiants of the Reign of Queen Elizabeth I, a collection of legal documents from the late 16th century. The name appears in reference to a land grant issued to a "Patrick Carmoney" in County Monaghan in the year 1589.
During the 17th century, the name CARMONEY gained prominence in the Ulster Plantation, a significant period of English and Scottish settlement in Ireland. Several families bearing this surname were recorded as receiving land grants in the counties of Monaghan and Armagh during this time.
In the 18th century, the CARMONEY name appeared in various parish records and land registries throughout County Monaghan and neighboring regions. One notable figure from this era was Terence CARMONEY (1712-1789), a prominent landowner and businessman who served as a magistrate in Monaghan.
As the Irish diaspora spread across the globe, the CARMONEY name traveled far and wide. In the late 19th century, Mary CARMONEY (1854-1932), a native of County Monaghan, immigrated to the United States and settled in Boston, where she became a respected educator and community leader.
Another notable individual was Michael CARMONEY (1872-1946), a successful businessman and entrepreneur from County Monaghan who established a thriving export business in the early 20th century. His company played a significant role in introducing Irish products to international markets.
The CARMONEY name has also been associated with literature and academia. One example is Dr. Patrick CARMONEY (1901-1978), a renowned scholar and author who taught at Trinity College Dublin and made significant contributions to the study of Irish history and folklore.
In more recent times, the name CARMONEY has continued to be represented in various fields. For instance, Eileen CARMONEY (1928-2018) was a celebrated artist and sculptor whose works were exhibited in galleries across Ireland and the United Kingdom.

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 Carmoney surname at the time of the 2020 Census, not any inherent property of the name itself.

Does the Census include every surname?

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
