The name DELAMORA also has ties to the region of La Mancha, famous for its association with the literary masterpiece "Don Quixote" by Miguel de Cervantes. In the 17th century, a notable figure named Diego DELAMORA (1612-1679) was a prominent landowner and agriculturist in the town of Campo de Criptana, where he cultivated extensive vineyards and olive groves.
Another notable individual with the DELAMORA surname was María DELAMORA (1745-1819), a celebrated painter from Seville who gained recognition for her portraiture and religious works during the Spanish Golden Age of art.

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.

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.
