Origin
The surname SOUTHERLIN is believed to have originated in England during the medieval period, specifically in the southern regions of the country. It is likely derived from the Old English words "suth" and "erling," which translate to "southern" and "person," respectively. This suggests that the name was initially given to individuals who hailed from the southern parts of England or were associated with those areas.
One of the earliest known references to the SOUTHERLIN surname can be found in the Domesday Book, a comprehensive record of landholdings and taxation compiled in 1086 on the orders of William the Conqueror. This ancient document mentions a landowner named Godric Sutherlin, whose estate was located in the county of Dorset, further solidifying the southern connection of the name.
During the 13th century, variations of the spelling emerged, including Sutherlin, Sutherlyne, and Sutherlynge. These variations were likely influenced by regional dialects and the evolving nature of language over time. It is also worth noting that some individuals with this surname may have been associated with specific place names, such as Sutherland or Southerland, which could have contributed to the development of the SOUTHERLIN spelling.
In the 14th century, a notable figure named William Southerlin (1310-1378) was recorded as a wealthy landowner and influential member of the gentry in the county of Somerset. His descendants continued to hold significant social and political positions throughout the following centuries.
Another prominent individual bearing this surname was Sir John Southerlin (1525-1598), a successful merchant and member of the Worshipful Company of Mercers in London. His legacy included substantial investments in the exploration and colonization efforts of the New World, contributing to the expansion of English influence across the Atlantic.
During the 17th century, the SOUTHERLIN surname gained further recognition with the birth of Reverend Thomas Southerlin (1643-1718), a respected clergyman and scholar who served as the Dean of Salisbury Cathedral. His theological works and sermons were widely circulated and respected among the ecclesiastical circles of his time.
In the 18th century, Captain James Southerlin (1732-1805) made a name for himself as a skilled navigator and explorer in the Royal Navy. His voyages to the West Indies and the Caribbean were documented in several nautical logs, contributing to the expansion of Britain's maritime knowledge and influence.
The 19th century saw the emergence of Sir Edward Southerlin (1821-1892), a prominent lawyer and politician who served as a Member of Parliament for several constituencies in England. His legal expertise and advocacy for social reforms left a lasting impact on the legislative landscape of his era.
Demographics
Among Census respondents with the surname Southerlin, the largest self-reported group is White at 91.7%. The next largest groups are Two or More Races (4.2%) and Black (2.5%).
The bar chart below shows how Southerlin 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 Southerlin surname at the time of the 2020 Census, not any inherent property of the name itself.
