Origin
The surname Loach is believed to have originated in England, with roots dating back to the 12th century. It is thought to have derived from the Old English word "lache," meaning a small stream or a ditch filled with water.
One of the earliest recorded instances of the name can be found in the Pipe Rolls of Shropshire from 1180, where a person named Robert de la Lache is mentioned. This indicates that the surname was likely formed as a topographic name, referring to someone who lived near a small body of water.
The name Loach has also been linked to various place names in England, such as Lache in Cheshire and Lach Dennis in Shropshire. These place names are believed to have originated from the same Old English word, further solidifying the connection between the surname and its geographical origins.
Throughout history, several notable individuals have borne the surname Loach. One of the earliest recorded examples is Sir John Loach (c. 1350-1420), a prominent English landowner and knight who served under King Henry IV during the Hundred Years' War.
Another prominent figure was William Loach (1528-1594), an English clergyman and scholar who served as the Archdeacon of Winchester during the reign of Queen Elizabeth I. He was known for his contributions to theological writings and his role in the governance of the Church of England.
In the literary world, Kenneth Loach (born 1936) is a renowned British filmmaker and social activist, known for his critically acclaimed works such as "Kes" (1969) and "I, Daniel Blake" (2016). He has received numerous accolades, including the Palme d'Or at the Cannes Film Festival.
The surname Loach has also been associated with notable figures in the field of science. One such individual was Sir Michael Loach (1907-1995), a British chemist and academic who made significant contributions to the understanding of organic compounds and their reactions.

Demographics
Among Census respondents with the surname Loach, the largest self-reported group is White at 78.1%. The next largest groups are Black (16.6%) and Two or More Races (2.3%).
The bar chart below shows how Loach 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 Loach surname at the time of the 2020 Census, not any inherent property of the name itself.
