Loudermilk
An English-style surname that likely began as a nickname or altered place-name based on an older word for “loud.”
The #6,924 most common surname in the United States (2010 Census) — about 1 in every 63,725 Americans shares it.
Etymology
Loudermilk is almost certainly an English surname in form, but its exact origin is uncertain. It appears to contain the element louder-, which may reflect an older pronunciation or spelling of “loud,” combined with milk, a word that is difficult to explain neatly in surname terms. Like many uncommon surnames, it may preserve a nickname, a dialect form, or an altered older name that has been reshaped over time.
History
The surname is found mainly in the United States, where it is especially associated with families of long-standing Appalachian and Southern roots. Its rarity suggests that it likely developed from a single local family line rather than from widespread independent origins. Because the form is unusual, later spellings may have been stabilized in America even if the name began more variably in earlier records.
