If you're referring to the famous musicians, then the answer is
no.
Steven Van Zandt (E Street Band) was born Steven Lento, and
later took his step-father's last name.
Ronnie Van Zant (Lynyrd Skynyrd) used his real name... but note
the different spelling.
However, Ronnie Van Zant was the brother of Johnny and Donnie
Van Zant (who both Lynyrd Skynyrd at different times).
Steven Van Zandt is the half-brother of actor Billy Van
Zandt.
