Dionne
A French surname that began as a personal name, often linked to Dion or Denis-type forms.
The #5,153 most common surname in the United States (2010 Census) — about 1 in every 45,484 Americans shares it.
Etymology
Dionne is a French surname that most likely developed from a personal name rather than from a place or occupation. It is commonly connected with the French name Dion, which can itself be a short form or variant of names ultimately tied to Greek Dionysios, the source of Denis and related names. In some families it may also reflect a diminutive or feminine-form spelling in French naming practice, but the exact pathway can vary by branch.
History
The surname is especially familiar in French-speaking regions, including France and French Canada, where many surnames were formed from given names. In North America it is often associated with Quebec and Acadian-descended families. The spelling with final -e is consistent with French orthography and helps preserve the surname's French identity.
