DeLuca
An Italian surname meaning “from Luke” or “of Luca,” originally pointing to a person named Luca.
The #2,263 most common surname in the United States (2010 Census) — about 1 in every 19,217 Americans shares it.
Etymology
DeLuca is an Italian surname built from the preposition de, meaning “of” or “from,” plus the personal name Luca. Luca is the Italian form of Luke, ultimately from the Latin name Lucas and the Greek Loukas, traditionally understood as “man from Lucania” or simply as a Christian personal name. In surname use, De Luca would originally have meant “son/family of Luca” or “belonging to Luca.”
History
The name is especially common in Italy and among Italian diaspora communities, particularly in the United States and Canada. In many records it appears both as De Luca and fused as Deluca, reflecting later spelling simplification in immigrant contexts. It is one of several very common Italian surnames formed from a father’s given name with de.

Fun fact
Because Luca was a very widespread Christian given name, DeLuca and similar surnames arose independently in many different Italian families.
