Origin
The surname Pembroke originated in England during the medieval period, deriving its name from the town of Pembroke in Wales. The name itself is a combination of the Welsh words "pen" meaning "head" and "bro" meaning "landing place" or "territory," referring to the location of the town at the head of a peninsula in Pembrokeshire.
The earliest recorded references to the surname Pembroke can be found in the Domesday Book of 1086, which was a comprehensive survey of landowners and tenants in England commissioned by William the Conqueror. The name appears in various spellings, including Penbroc and Pembroc, reflecting the evolution of the spelling over time.
One of the earliest known individuals bearing the surname Pembroke was Walter de Pembroke, who lived in the 12th century and served as a knight under King Henry II. He was granted lands in Pembrokeshire and played a significant role in the Welsh Marches, the border region between England and Wales.
Another notable figure with the Pembroke surname was Aymer de Valence, Earl of Pembroke (c. 1265-1324), a powerful nobleman and military commander during the reigns of Edward I and Edward II. He was involved in various conflicts, including the Scottish Wars of Independence and the Baronial Wars against the Crown.
In the 15th century, Jasper Tudor, Earl of Pembroke (1431-1495), was a prominent figure and the uncle of King Henry VII. He played a crucial role in the Wars of the Roses and was instrumental in securing the Tudor dynasty's claim to the English throne.
William Herbert, 1st Earl of Pembroke (c. 1501-1570), was a prominent courtier and statesman during the reigns of Henry VIII, Edward VI, and Elizabeth I. He held several important positions, including Lord President of Wales and Lord Lieutenant of Wiltshire.
Sir Philip Sidney (1554-1586), a renowned poet, courtier, and soldier, was also a member of the Pembroke family. He was closely associated with the court of Elizabeth I and is remembered for his influential works, including "Astrophel and Stella" and "The Defence of Poesy."
Throughout its history, the Pembroke surname has been closely tied to the town and region of Pembrokeshire in Wales, reflecting the ancestral roots and territorial connections of those who bore the name. The name's enduring presence in historical records and its association with notable figures underscore its significance in English and Welsh history.
Demographics
Among Census respondents with the surname Pembroke, the largest self-reported group is White at 85.4%. The next largest groups are Black (7.9%) and Hispanic (3.2%).
The bar chart below shows how Pembroke 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 Pembroke surname at the time of the 2020 Census, not any inherent property of the name itself.
