I was named after a girl my grandpa knew growing up. Mylene is also my mom's middle name. Elizabeth is all my parents could come up with that sounded good with Mylene.
The girls's first names are just names we liked. Kaija is a Finnish name so that goes back to DH's Finnish/Swedish heritage. Her middle name is Jane and that is after DH's grandma and is also MIL's middle name. Kolbie is an English name and I'm mostly English, I guess.

Mostly we just liked it. Her middle name is also Elizabeth, after me.
