Origin
Meaning and history of Glasco
The given name Glasco is believed to have its origins in the Gaelic language, which was spoken by the Celtic people of Scotland and Ireland. The name is thought to be derived from the Old Gaelic words "glas" meaning "green" and "cu" meaning "hollow" or "valley." Together, these words would have formed a compound name that could be interpreted as "green valley" or "green hollow."
The earliest recorded instances of the name Glasco can be traced back to medieval Scotland, where it was likely used as a descriptive name for someone who lived in a verdant valley or near a green hollow. In those times, it was common for people to be given names that reflected their physical surroundings or occupation.
One of the earliest notable individuals to bear the name Glasco was a Scottish clergyman named Glasco of Moray, who lived in the 12th century. He served as the Bishop of Moray from 1162 until his death in 1199. Another prominent figure was Glasco of Arbroath, a Scottish scholar and philosopher who lived in the 13th century and was known for his work in logic and metaphysics.
In the 15th century, a Scottish nobleman named Glasco MacDonald was recorded as the chief of the Clan Donald, one of the most powerful clans in the Scottish Highlands. He played a significant role in the clan's conflicts with rival clans and the Scottish crown during that turbulent period.
Moving forward in time, a notable figure named Glasco Baillie was born in Edinburgh, Scotland, in 1692. He was a renowned mathematician and philosopher who made important contributions to the development of calculus and the study of mechanics.
Lastly, in the 19th century, a Scottish author and poet named Glasco Buchanan was born in 1828. He is best known for his romantic poems and novels that celebrated the beauty of the Scottish Highlands and the culture of the Scottish people.
While the name Glasco may have fallen out of widespread use in modern times, its historical roots and associations with Scotland's rich cultural heritage continue to make it a distinctive and intriguing given name.

FAQ
Glasco: questions and answers
How many people in the U.S. are named Glasco?
Name Census puts the figure at roughly 3 living Americans. We arrive at this by taking every SSA birth registration for Glasco going back to 1880 and adjusting each cohort for expected survival using CDC actuarial life tables. The result is an age-weighted living-bearer count, not a raw birth total. That works out to about 1 in 114,251,446 US residents.
Is Glasco a common name?
We classify Glasco as "Very Rare". It ranks above 4.9% of all first names in the SSA dataset by living bearers. Across the full history of the data, 16 babies have been registered with this name.
When was Glasco most popular?
The single biggest year for Glasco was 1943, when 6 babies received the name. The fact that the average living Glasco is about 88 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
What does the SSA popularity chart show?
The chart tracks births, not the number of people alive with the name today. Each point shows how many babies were given the name Glasco in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Glasco a male name?
Yes, 100.0% of people registered as Glasco in the SSA data are male. You can see the full per-sex comparison in the gender distribution section above, which includes the latest year rank, birth count, and peak year for each sex.
Is Glasco still being used today?
Yes. The SSA still recorded Glasco in 2024, and the page above shows its latest-year rank where available. A name can be well past its peak and still remain in steady use, especially if it built up a large population over earlier decades.
Why can a name have a lot of living bearers even if it is not trendy now?
Because living-bearer counts and current baby-name popularity measure different things. A name like Glasco can build up a very large population over many decades, even if fewer parents are choosing it now than they did at its peak.
Where does this data come from?
First-name figures come from the Social Security Administration's national baby name files, which cover every name on a birth certificate from 1880 to 2024. Living-bearer estimates layer in CDC actuarial life tables broken out by sex to account for mortality. The population baseline (342,754,338) is the Census Bureau's latest national estimate. You can read the full calculation on our methodology page.
Does every first name have Census demographic data?
No. The public Census first-name release only covers names that met the Bureau's publication rules, so many rarer names in the SSA files do not have a published Census demographic snapshot. In those cases, the page still shows the SSA trend, gender history, and state data.
