Origin

Meaning and origin of Jameson

The surname Jameson is of Scottish origin, derived from the medieval personal name "James" combined with the patronymic suffix "-son", meaning "son of James". The name James itself is derived from the Latin name "Iacobus", which in turn came from the Hebrew name "Ya'aqov" or Jacob.

The earliest recorded instances of the name Jameson can be traced back to the late 12th century in Scotland. One of the earliest recorded bearers of the name was Robert Jamesson, who was listed in the Ragman Rolls of 1296, a record of Scottish landowners who swore fealty to King Edward I of England.

In the 15th century, the name Jameson was particularly prominent in the Scottish Lowlands, particularly in the counties of Lanarkshire and Renfrewshire. The name was also found in the Borders region and in parts of northern England, likely due to the movement of Scottish families across the border.

Notable historical figures with the surname Jameson include Robert Jameson (1774-1854), a Scottish naturalist and mineralogist who served as Regius Professor of Natural History at the University of Edinburgh. Another notable bearer of the name was Leander Starr Jameson (1853-1917), a British colonial administrator and leader of the famous Jameson Raid into the Transvaal in 1895.

In the literary world, the name Jameson is associated with the Irish novelist and playwright James Augustine Aloysius Joyce (1882-1941), who was given the middle name "Aloysius" in honor of the Jesuit priest Aloysius Gonzaga. Joyce's friend and fellow writer Francis Stuart (1902-2000) was also known by the pen name "Jameson".

Other notable bearers of the name include John Jameson (1773-1823), the founder of the Jameson Irish Whiskey distillery in Dublin, and Sir Leander Rees Jameson (1853-1917), a British colonial administrator and leader of the Jameson Raid.

While the surname Jameson is found globally today, its origins can be traced back to medieval Scotland, where it was initially derived from the personal name James and the patronymic suffix "-son".

Demographics

Ancestry and ethnicity for Jameson

Among Census respondents with the surname Jameson, the largest self-reported group is White at 81.9%. The next largest groups are Black (7.6%) and Two or More Races (4.1%).

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

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.
