Merz
A surname that is often treated as a short form of a personal name, though in some cases it may also echo the month name March/Merz.
The #7,684 most common surname in the United States (2010 Census) — about 1 in every 71,452 Americans shares it.
Etymology
The surname Merz is usually explained as a shortened form of a given name, especially a pet form of names such as Meinhard and related Germanic names. Older surname scholars also noted that forms like Menz, Merz, and similar short names often grew from longer personal names by dropping the middle syllables. In some German-speaking areas, however, Merz was also linked to the month name März (March), so the surname may have more than one source in different families.
History
The name appears in German surname lists alongside other clipped forms such as Menz, Mez, and Merzel, which suggests a long history as a nickname-based family name. In older scholarship, it is usually grouped with south German and Swiss naming patterns, though the exact origin can vary by family line. The spelling Merz became stable in many places, while related forms continued to circulate in regional dialects and local records.
