Origin
The surname Roache has its origins in medieval England, where it first emerged as a locational name derived from the Old English words 'hreac' or 'hreacca', meaning a rick or stack of hay or grain. The name was likely given to someone who lived near a distinctive rick or haystack.
This surname can be traced back to the 13th century, with one of the earliest recorded instances appearing in the Subsidy Rolls of Staffordshire in 1327, where a William del Rache is mentioned. The prefix 'del' suggests a locational origin, indicating the family resided near a distinctive rick or haystack at the time.
In the Domesday Book of 1086, there are references to several places with similar names, such as Rache in Cheshire and Rachebi in Derbyshire, which may have contributed to the development of this surname in those areas.
The earliest known bearer of the Roache surname was Sir John Roache, a prominent landowner and knight who lived in Cheshire during the 14th century. Another notable figure was Robert Roache (1563-1622), a renowned English clergyman and theologian who served as the Bishop of Chester from 1607 until his death.
In the 16th century, the surname appeared in various spellings, including Roche, Roache, and Roach, reflecting the regional variations in pronunciation and spelling at the time. One example is Richard Roache (1547-1624), an English politician who served as a Member of Parliament for Andover in 1597.
Another significant bearer of this surname was Sir William Roache (1673-1735), a successful merchant and politician who served as Lord Mayor of London in 1708-1709. He was also a Member of Parliament for the City of London from 1713 to 1722.
During the 17th and 18th centuries, the Roache family was well-established in Cheshire and Lancashire, with several members holding prominent positions in local government and society. One such individual was John Roache (1693-1768), a wealthy landowner and Justice of the Peace in Cheshire.
Demographics
Among Census respondents with the surname Roache, the largest self-reported group is White at 51.3%. The next largest groups are Black (38.2%) and Hispanic (4.8%).
The bar chart below shows how Roache 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 Roache surname at the time of the 2020 Census, not any inherent property of the name itself.

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.
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.
