Origin
Meaning and origin of Sivigny
The surname Sivigny has its origins in France, dating back to the medieval period. It is believed to have originated from the French village of Sivigny, located in the Champagne region. This place name is derived from the Latin word "silva," meaning forest or woods, indicating that the name likely referred to someone who resided near or in a forested area.
One of the earliest recorded instances of the name Sivigny can be found in the Cartulaire de l'Abbaye de Saint-Pierre de Châlons, a 13th-century manuscript that documented various transactions and legal affairs in the region. In this manuscript, a certain Guibert de Sivigny is mentioned as a witness to a land transfer in 1218.
During the 14th century, the surname Sivigny appears in several historical records, including the Taille de Troyes, a tax roll from the city of Troyes in 1384. This document lists several individuals bearing the name Sivigny, suggesting that the family had established itself in the region by that time.
In the 15th century, a notable figure with the surname Sivigny was Jean de Sivigny, a renowned knight who served under King Charles VII of France during the latter part of the Hundred Years' War. Jean de Sivigny was born around 1410 and is known for his bravery and military exploits, particularly in the Battle of Patay in 1429.
Another prominent individual with the surname Sivigny was Nicolas de Sivigny, a 16th-century lawyer and judge who served in the Parlement of Paris. Born in 1520, Nicolas de Sivigny gained recognition for his legal expertise and authored several treatises on French law.
In the 17th century, the name Sivigny appeared in various records related to the French nobility. One notable example is Marie-Anne de Sivigny, born in 1645, who married into the prestigious Montmorency family and became the Countess of Logny.
Throughout history, other variations of the surname have been observed, such as Syvigny, Sivigni, and Sivigney. These variations likely emerged due to regional dialects, spelling conventions, or scribal errors in historical documents.

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 Sivigny 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.
