Lacasse
A French surname usually meaning “the box” or “the chest,” likely referring to a container maker, a house sign, or a place by a storeroom.
The #9,790 most common surname in the United States (2010 Census) — about 1 in every 93,361 Americans shares it.
Etymology
Lacasse is a French surname built from the definite article le/la plus casse/casse, a word associated with a box, chest, or case. In surname use, it can point to someone who made or sold boxes or chests, or to a house or place identified by a sign with that image. In some cases it may also be locational or nickname-like rather than strictly occupational.
History
The name is found in French-speaking regions, especially in France and later in French Canada. Like many French surnames beginning with the article la-, it often became fixed as a hereditary family name in the early modern period. In North America, Lacasse is especially associated with Quebec and French-Canadian families.
