Inspired by the Astrid Weissman character from The Marvelous Mrs. Maisel:

A muggle woman who marries into a wizarding family and she is overzealous about fitting in and being a proper "witch". She learns everything about magical history so she throws random "Today is the anniversary of the battle between two random medieval wizards", she dresses overly much in magical clothes.

They can also be Jewish wizards because basically for anyone who hasn't seen the show, Astrid marries into a Jewish family and she's trying super hard to fit in and she's taken the whole Being a Jew thing super seriously whereas her married family are way more chill. xD
