I have 2 siblings with very common names, and mine is pretty common, but one sibling has a very unusual name.
She got lots and lots of comments growing up - lots of questions about it, lots of people asking her what her siblings were called (obviously expecting other unusual names), lots of people commenting that her name is unusual.
Now as it happens she’s an extrovert who loves to chat and loves attention, so that’s never been a bother for her.
However one of the others is shy, feels “picked on” very easily, generally a sensitive soul. Even our parents have commented that it’s a good thing she didn’t get the unusual name as it would have really bothered her.
So....not sure that’s helpful advice really. It depends on your child’s personality, which you can’t predict!
Personally I find one really common and one really unusual name a bit odd, especially if they’re the same gender. It feels a bit like the “interesting” name got used up!
