Origin
Meaning and origin of Crimin
The surname Crimin originated in Ireland during the 11th century. It is derived from the Gaelic word "crimín" which means "wild garlic" or "crow". The name likely referred to someone who lived near a wild garlic patch or a place where crows gathered.
The earliest recorded instance of the name can be found in the Annals of Ulster, a chronicle of medieval Irish history, which mentions a "Crimín Ua Ruairc" in the year 1072. The Ua Ruairc family were a prominent clan in the region of modern-day County Leitrim.
In the 13th century, the surname appeared in various forms such as Cremyn, Crimyn, and Crymyn in various Irish records and manuscripts. One notable bearer of the name was Tadhg Crimin, a renowned Irish poet and scholar who lived in the late 14th century.
The surname also has connections to several place names in Ireland, such as Crimin Hill and Crimin Lough in County Leitrim, which likely derived their names from early bearers of the surname who lived in those areas.
Notable individuals with the surname Crimin throughout history include:
1. Aodh Crimin (c. 1550 - 1620), an Irish nobleman and chief of the Crimin clan in County Leitrim.
2. Seán Crimin (1685 - 1746), an Irish Catholic priest and historian who wrote extensively about the Penal Laws against Catholics in Ireland.
3. Bridget Crimin (1773 - 1848), an Irish immigrant to the United States who was one of the first settlers in what is now Chicago, Illinois.
4. James Crimin (1840 - 1905), an Irish-American lawyer and politician who served as a member of the New York State Assembly.
5. Michael Crimin (1868 - 1932), an Irish-born American labor leader and trade unionist who played a significant role in organizing workers in the early 20th century.

The bar chart below shows how Crimin bearers described their own race and ethnicity on the 2020 Census form. 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 Crimin 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.
