Loucks
A surname of uncertain but likely Germanic or Dutch origin, often treated as a spelling variant of names built on the old name Luke/Lucas or a related regional form.
The #6,318 most common surname in the United States (2010 Census) — about 1 in every 57,143 Americans shares it.
Etymology
Loucks is usually explained as a surname formed from a personal name, most likely a regional or shortened form related to Luke or Lucas. In some families it may reflect Dutch or German naming habits, where surnames developed from a father's given name and were later Anglicized in spelling. The ending -s commonly marks "son of" or belonging to a person named Louck/Luke.
History
The name is best known in North America, where it appears among families of Dutch, German, and British Isles background. Like many surnames of this type, its spelling was not fully standardized, so related families may appear as Loucks, Louk, Loucks, or other local variants in older records. The modern distribution suggests later consolidation in the United States and Canada.

Fun fact
Because Loucks is often a surname-by-spelling rather than a single fixed medieval form, different Loucks families may not share the same original ancestor.
