Hollywood is full of celeb brothers and sisters, but not everyone can be famous. There are tons of non-famous people with famous siblings who pop up now and then on celeb gossip sites. For example, did you know that pop powerhouses Britney and Jamie-Lynn Spears aren't the only scions of the Spears dynasty? In fact, their oldest sibling is Bryan, who's produced for both his siblings.

And then there's Braison Cyrus, the brother of pop star Miley Cyrus. He doesn't seem likely to remain one of the unknown siblings of well-known siblings, as he's gaining fame as a model and singer. As far as unknown brothers of stars, don't miss Andrew Wilson, sibling of funnymen Luke and Owen. And then there are the unknown sisters of stars - have you heard of Alana Hadid? She's a stylist and the older half-sister of models Bella and Gigi Hadid.

Whether they're the black sheep of their families or rising stars themselves, these unknown siblings of celebrities have names worth knowing.

The brother of savant-academic-actor James and baby-faced hunk Dave, Tom Franco is the lesser-known, but equally-talented, third Franco brother. Dave quipped:

"For people who have met all three of us, Tom Franco is the unanimous favorite Franco. He’s the best one - the best-looking, the sweetest, the nicest, greatest guy to be around. We keep him to ourselves. He’s our little secret."

A California-based artist, Tom seems to be juggling multiple artistic ventures at any given time. He renovates lofts, paints murals, and helps run a Berkeley-based nonprofit artists' collective.
