Mangrum
A surname most likely built from an older place-name or personal name element, though its exact origin is uncertain.
The #7,772 most common surname in the United States (2010 Census) — about 1 in every 72,306 Americans shares it.
Etymology
Mangrum is probably an English-language surname, but its exact derivation is not securely established. In many cases, surnames of this shape arose either from a now-lost local place-name or from an older personal name that has since been altered in pronunciation and spelling. The final element -rum is suggestive of a place-name ending, but the first element remains unclear, so the meaning cannot be stated with confidence.
History
The surname is found chiefly in the United States today, which often reflects early modern migration and later spelling stabilization rather than a clear surviving homeland form. Because the name is relatively uncommon and not well documented in standard etymological reference works, its early history is harder to trace than that of more common English surnames. Modern bearers may descend from a small number of related families whose spelling became fixed in American records.
