Origin
The surname Trogdon is believed to have originated in England, likely during the medieval period. It is thought to be derived from an Old English place name, possibly "Troc's Valley" or "Troc's Hill," where "Troc" was a personal name. The earliest known spelling variations of the name include Trockedon, Trokeden, and Troggedene.
One of the earliest recorded instances of the surname Trogdon can be found in the Domesday Book of 1086, a comprehensive record of landowners and tenants in England commissioned by William the Conqueror. The name appears as "Trochedon," referring to a landowner or tenant in the county of Somerset.
In the 13th century, a reference to a "William Troggedene" can be found in the Pipe Rolls of Gloucestershire, a historical record of financial accounts and transactions in the county. This suggests that the surname had spread to other parts of England by this time.
During the 16th century, the Trogdon surname appeared in various parish records and court documents across England. Notable individuals from this period include John Trogdon, a merchant from Bristol who was born in 1532, and Thomas Trogdon, a landowner from Wiltshire who was born in 1568.
In the 17th century, the Trogdon name gained prominence through the exploits of Sir William Trogdon, a military officer who served in the English Civil War. Born in 1620 in Dorset, he fought for the Parliamentarian forces and was knighted for his bravery in battle. He died in 1689.
Another notable figure bearing the Trogdon surname was Edward Trogdon, a prominent lawyer and judge who lived in the late 18th century. Born in 1745 in Oxfordshire, he served as a judge in the Court of Common Pleas and was widely respected for his legal expertise and integrity.
As the centuries passed, the Trogdon surname continued to be found throughout England, with various branches of the family settling in different regions. While the origins of the name can be traced back to medieval times, its endurance and spread across the country reflect its deep roots in English history and culture.
Demographics
Among Census respondents with the surname Trogdon, the largest self-reported group is White at 87.2%. The next largest groups are Black (5.9%) and Two or More Races (4.2%).
The bar chart below shows how Trogdon 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 Trogdon 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.
