Gender: Male Meaning of Septimus: "the seventh son" Origin of Septimus: Latin

The name Septimus is a boy's name of Latin origin meaning "the seventh son". Septimus and is often added to lists like Best One-of-a-Kind Names for Boys and discussed in our forums with posts like "Names on NB that make you go WOW!".

From the experts:

Septimus is one of the more dashing of the birth-order Latin number names that were revived by the Victorians. So even if you don't anticipate son number 7, you might be bold enough to consider this relic, certainly preferable to sixth-son name Sextus.

Septimus was popularized by the Roman Emperor Septimus Severus, a patron of arts and letters. There was a Septimus in Wilkie Collins's The Moonstone, in Dickens's The Mystery of Edwin Drood, and in Trollope's Barchester novels. Probably it is most familiar to modern readers as one of the principal characters in Virginia Woolf's Mrs. Dalloway, and as Harry Potter wizard, Septimus Weasley. There is also Septimus Heap, a series of bestselling fantasy novels by Angie Sage.
