As in the question being. Is it deemed as possible to connect the [name_u]Van[/name_u] der names such as [name_u]Van[/name_u] der Bilt. Creating, Vanderbilt? I have a beautiful name in mind that would make a wonderful surname but need to get the idea if it is normal too?
I think it definitely would be an unusual name but on the other side a lot of surnames are being used as first names today. So why not go for it if you like it.
I have a friend whose surname is [name_m]Von[/name_m] der Embse, but some people in her family use Vonderembse instead. I also know [name_u]Van[/name_u] den Bergs who have family members that use Vandenberg. It’s definitely doable.
