Last names that start with Van/Von?

What are some last names that start with Van or Von?

I'm talking with a friend and we came across a picture with this other girl we went to school with. We can't remember her last name and it's driving us crazy! I'm pretty sure it started with Van (could have been Von though).

She's married now, so her name on social media is different. Her profiles are private, so we can't go through friends lists to look for her family.

I know this probably sounds super creepy, but I promise you it's not! Lol
