Origin
Meaning and origin of Mummert
The surname Mummert originated in Germany and is believed to have derived from the Middle High German word "mummen," which means "to murmur" or "to mumble." This suggests that the name may have been initially associated with someone who spoke in a soft or indistinct manner.
In the 16th century, the surname Mummert was first documented in various regions of Germany, particularly in the areas around the Rhine River. Some of the earliest recorded spellings of the name include Mummert, Mummard, and Mummhardt.
While there are no known historical references to the name Mummert in major manuscripts or records like the Domesday Book, the surname can be traced back to the 15th century in certain German church records and local archives.
One of the earliest recorded individuals with the surname Mummert was Hans Mummert, born in 1542 in the town of Mainz, Germany. He was a respected miller and landowner in the region.
Another notable figure was Johann Mummert (1612-1681), a Lutheran pastor and theologian who served in the town of Wittenberg, where Martin Luther had famously nailed his 95 Theses to the church door.
In the 18th century, a family of Mummerts emigrated from Germany to Pennsylvania, USA, where they settled in the area now known as York County. One of the early settlers was Jacob Mummert (1732-1812), a farmer and miller who played a role in the local community.
During the 19th century, a prominent figure with the surname Mummert was August Mummert (1825-1899), a German-American industrialist and inventor who founded the Mummert Knitting Machine Company in Reading, Pennsylvania.
Another individual of note was Dr. Carl Mummert (1876-1942), a German physician and researcher who made significant contributions to the field of immunology and the study of bacterial toxins.

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 Mummert 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.
