About sibling names
Names for siblings usually match in one way and differ in another: they share a first letter (Leo and Lucas), rhyme (Jordan and Logan), or have the same length, while still sounding like two different people.
Every pair is made from the 1,400 most common first names in Wikidata, so both names are real and well known. Pick the genders and how the names should match, then save the pairs you like.
How to choose sibling names
Say both names together, in both orders, the way you will call them.
Avoid pairs that sound alike when shouted: Aaron and Erin are easy to mix up.
Same first letter works well on paper; rhyming pairs are more playful.
