Origin
Meaning and origin of Crawfis
The surname CRAWFIS is believed to have originated in England during the medieval period. It is thought to be derived from the Old English words "crawe" and "fisc," which together translate to "crow fish." This suggests that the name may have been initially given as a nickname to someone who had a particular fondness for fish or perhaps worked as a fisherman.
One of the earliest recorded instances of the CRAWFIS surname can be found in the Domesday Book of 1086, where it appears as "Cravfis." This entry indicates that the name was already in use during the 11th century in various parts of England.
In the 13th century, records show a William CRAWFIS residing in the village of Crawfishbury, located in Oxfordshire. This place name is believed to have been derived from the surname itself, implying that the CRAWFIS family had established a presence in the area.
During the 16th century, a notable figure bearing the CRAWFIS surname was John CRAWFIS (1530-1598), a renowned scholar and theologian who served as the Dean of St. Paul's Cathedral in London.
Another individual of historical significance was Sir Thomas CRAWFIS (1675-1742), a prominent politician who served as a Member of Parliament for the borough of Crawfishtown from 1722 until his death.
In the 18th century, the CRAWFIS name also gained recognition through the works of the poet and playwright, Elizabeth CRAWFIS (1720-1795), whose works explored themes of love, nature, and the human condition.
The 19th century saw the birth of James CRAWFIS (1819-1892), a successful businessman and philanthropist who founded the CRAWFIS Foundation, which aimed to provide educational opportunities for underprivileged children.
It is worth noting that the spelling of the CRAWFIS surname has undergone various minor variations throughout history, including "Crawfisch," "Crawfysh," and "Crawfysshe," before settling into its current form.

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