Ulalume

Umbrette

Made famous by the iconic and macabre character Wednesday Addams, this name has the spooky and Halloween-inspired feel that some parents might be looking for. The character has appeared in various adaptations of The Addams Family over the years, but the 2022 television series starring Jenna Ortega has given the name an unexpected boost in popularity. 
 
Wednesday originates from the Anglo-Saxon times, when it was known as Wōdnesdæg, or Woden's Day -- Woden being the English equivalent to the Norse god Odin -- who is also linked to the Roman god Mercury. Cartoonist Charles Addams who created the character of Wednesday Addams however chose her name based on the popular Monday's Child rhyme, in which "Wednesday's child is full of woe."
 
A choice that is gloomy, offbeat, quirky, wordy and celestial all at once, Wednesday has been quietly climbing up the charts since the 60s, but has been gaining increasing momentum. Not only has the newest adaptation made it feel more familiar, but actors Rupert Grint and Georgia Groome chose if for their daughter in 2020, making it feel more usable for everyone else. 
 
Given to 75 girls in the US in 2024, it's not quite so popular as the sunny Sunday yet, but it is on the rise. 
 Vintage nicknames Wendy and Winnie might make it feel more approachable, or, if you love it but find it a bit much as a given name, Gwendolyn Daisy "Wednesday" perhaps?
