Delierre

Delierre is a surname of French origin. It is commonly treated as a habitational or toponymic name, often interpreted as de lierre, meaning “from the ivy,” a reference either to a landscape feature or to a place named Lierre or Lier in French- or Flemish-speaking regions. The form Delierre reflects typical French phonetic and orthographic developments in compound surnames.

Historically, Delierre appears in northern France and nearby Belgium from the medieval period, with the name later spreading to other Francophone areas through migration. In modern times it is found in Canada, the United States, and other countries with French-speaking communities. Variant spellings such as Delier, De Lierre, or De Lier are sometimes recorded, reflecting regional and historical orthography.

Today, Delierre remains relatively uncommon. Bearers of the name are reported in a range of occupations and do not form a single institutional association. The surname can be a starting point for genealogical research into family origins in Francophone Europe, especially in regions around the historical counties and towns associated with ivy-draped landscapes.
