Origin
Meaning and origin of Sensenig
The surname SENSENIG has its origins in the German language and can be traced back to the 16th century. It is believed to have originated in the Rhineland region of Germany, specifically in the areas around the towns of Sensenich and Sinsernich. The name is derived from the Old German word "sinsling," which means "one from the place of the small stream."
One of the earliest recorded instances of the SENSENIG surname can be found in the church records of the village of Sensenich, dating back to 1585. These records mention a certain Hans Sensenig, who was a farmer and landowner in the area. It is likely that this individual and his family were among the first to bear the surname.
In the 17th century, the SENSENIG name began to spread beyond the Rhineland region as families migrated to other parts of Germany and neighboring countries. Some SENSENIGS settled in the Palatinate region, while others ventured as far as Switzerland and the Netherlands.
The earliest known SENSENIG to emigrate from Europe to the American colonies was Hans Jerg Sensenig, who arrived in Pennsylvania in 1737. He was part of the wave of German Palatine immigrants who settled in the fertile farmlands of Lancaster County, Pennsylvania. Hans Jerg Sensenig and his descendants played a significant role in the early development of the Pennsylvania Dutch community.
One notable figure from the SENSENIG family was John Sensenig (1771-1846), a farmer and businessman from Warwick Township, Lancaster County. He was a prominent member of the Mennonite community and served as a deacon in the local church. Another important SENSENIG was Abraham Sensenig (1798-1874), who was a successful farmer and landowner in West Earl Township, Lancaster County.
In the 19th century, some SENSENIGS ventured westward, following the frontier as it expanded across the United States. One such pioneer was Christian Sensenig (1815-1891), who settled in Elkhart County, Indiana, and became a prosperous farmer and community leader.
Another noteworthy SENSENIG was Samuel Sensenig (1842-1912), a prominent educator and founder of the Sensenig Academy in Lititz, Pennsylvania. This private school was renowned for its rigorous academic standards and attracted students from across the region.
As the SENSENIG surname spread throughout the United States and Canada, it maintained its strong ties to its German roots and the Mennonite faith. Today, the name can still be found in significant numbers in areas with large populations of Pennsylvania Dutch and Mennonite descendants, such as Lancaster County, Pennsylvania, and various communities in Ohio and Indiana.

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

Is this page using the latest Census data?

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.
