Origin
Meaning and origin of Conro
The surname CONRO is believed to have originated in Ireland, specifically in the southern regions of the country. It is thought to be derived from the Old Irish Gaelic word "conra," which translates to "victorious" or "conquering." The earliest records of this surname can be traced back to the 11th century.
In the Annals of the Four Masters, a medieval Irish chronicle, there are mentions of individuals bearing the name CONRO, or variations thereof, such as Conroy or Conrey. One notable entry from the 12th century references a Conchobhar Ó Conrói, who was a chieftain of the Uí Failge, a prominent Irish clan.
The CONRO surname is also found in several ancient manuscripts and records, including the Annals of Ulster and the Book of Leinster, both of which date back to the 12th century. These references suggest that the name was well-established in Ireland during the Middle Ages.
One of the earliest documented individuals with the surname CONRO was Malachy Conroy, who was born in County Offaly, Ireland, in the late 15th century. He was a renowned scholar and poet, known for his works in the Irish language.
Another notable figure was Felim Conroy, born in County Longford, Ireland, in the 16th century. He was a prominent leader during the Irish Rebellion of 1641 and played a significant role in the resistance against English rule.
In the 17th century, a family of CONRO landowners in County Westmeath, Ireland, gained prominence. One member of this family, James Conroy, born in 1658, was a successful merchant and politician who served as a member of the Irish Parliament.
The CONRO surname was also found in other parts of Ireland, such as County Mayo, where a branch of the family settled in the 18th century. One of their descendants, Michael Conroy, born in 1792, was a respected educator and writer who published several works on Irish history and culture.
Throughout the 19th century, many individuals with the CONRO surname emigrated from Ireland to other parts of the world, including the United States, Canada, and Australia. This diaspora played a significant role in the global distribution of the name.

The bar chart below shows how Conro 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 Conro surname at the time of the 2020 Census, not any inherent property of the name itself.

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Conro (2000, 2010, 2020).
Does the Census include every surname?
No. The Census Bureau only publishes surnames that appeared at least 100 times in a given decennial Census. That means very rare surnames are excluded entirely, and a surname can appear in one Census release but disappear from a later one if it falls below the reporting threshold.
Why don't the ancestry percentages always add up to exactly 100%?
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy. For 2020, the Bureau also published raw group counts rather than direct percentages, so Name Census converts those counts back into shares for comparability across census years.
