Origin
Meaning and origin of Heermance
The surname HEERMANCE originates from the Netherlands and dates back to the 17th century. It is derived from the Dutch words "heer" meaning "lord" and "mans" meaning "man," suggesting it was initially a descriptive name for a manorial lord or someone who worked for a lord.
HEERMANCE was first documented in the Dutch province of Gelderland, particularly in the areas around Arnhem and Nijmegen. Variations in spelling include Heermans, Harmans, and Hermans.
One of the earliest recorded instances of the name comes from a baptismal record in Arnhem, dated 1632, for a child named Johannes Heermance. Another early reference is found in the Gelderland leenaktenboeken (feudal records) from 1647, which mentions a Gerrit Heermance.
In the late 17th century, several individuals with the surname HEERMANCE emigrated from the Netherlands to New Netherland, a Dutch colony in present-day New York. Notable early settlers include Marten Heermance, who arrived in 1659 and settled in Beverwyck (now Albany), and his son Johannes Heermance (1664-1740), who became a prominent landowner and mill operator in the Hudson Valley.
Another prominent figure was Reverend Theodorus Jacobus Heermance (1728-1800), a Dutch Reformed minister who served congregations in New York and New Jersey. He was born in Rhinebeck, New York, to Johannes Heermance and Geertje Tietsoort.
In the 19th century, Theodorus E. Heermance (1805-1884) was a respected lawyer and judge in New York City. He was born in Rhinebeck to Jacob Heermance and Maria Van Vredenburgh.
Ezekiel Heermance (1793-1868), born in Livingston, New York, was a prominent farmer and landowner in Columbia County. He was also a deacon in the Dutch Reformed Church.
The HEERMANCE surname has been well-documented throughout the history of the Dutch settlers in the Hudson Valley region of New York, with many descendants still residing in the area today.

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

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
