Meaning and origin of Hallock
The surname HALLOCK is of English origin and dates back to the 11th century. It is believed to have originated from a place name in the county of Shropshire, England, where it was first recorded as "Hauloc" or "Haloc." The place name is thought to be derived from the Old English words "heal" meaning "hall" or "manor" and "ac" meaning "oak."
In the Domesday Book of 1086, the first comprehensive record of landowners in England, there are several entries for individuals with the surname HALLOCK or similar spellings, such as "Haloc" and "Hauloc." These entries suggest that the name was already established in various parts of England by the late 11th century.
One of the earliest recorded instances of the surname HALLOCK can be found in the Pipe Rolls of Staffordshire from 1199, which mention a "William de Haloc." The "de" prefix in his name indicates that he was from the place named Haloc.
In the 13th century, the surname appears in various records with spellings like "Hallok," "Halloke," and "Hallock." In 1273, a John Hallok is mentioned in the Hundred Rolls of Oxfordshire, while a Robert Hallock is recorded in the Subsidy Rolls of Worcestershire in 1327.

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.

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 Hallock surname at the time of the 2020 Census, not any inherent property of the name itself.

Does the Census include every surname?
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.
Why don't the ancestry percentages always add up to exactly 100%?
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.
