Etymology
Heloise is a Nordic form of a similar French name, which is probably from the Germanic name Helewidis, composed of the elements heil, meaning "hale, healthy", and wid, meaning "wide". It is sometimes associated with the Greek word for "sun", helios, or the English name Louise, thought there is not likely an etymological connection.

Beaufort is a French locational surname that is derived from various places in France. It is composed of the elements beau, meaning "beautiful", and fort, meaning "strong place, fortress".

The name Lestrange echoes the French phrase l'étrange, literally "the strange one". In Old French, estrange means "foreigner". The surname may allude to English journalist Roger L'Estrange, who was known for opposing religious toleration and for being involved in plots against the government of William and Mary, similar to the Lestranges' intolerance about blood purity and involvement in the Death Eaters organization.
