I'm trying to think about instances in which a parent and child were both fund managers, but the child worked to get away from the parent. (Mostly these are father-son pairs, with Roy and Rose Papp as the only father-daughter one that comes to mind.)
The Yacktmans (Yacktman and YCG) come immediately to mind. The Dodsons (Parnassus and Frank Value). The Bogles, sort of (Vanguard and Bogle).
Setting aside the family-run boutiques (Crawford, Queens Road, Muhlenkamp - eeee!), can you think of other instances were the scion struck out on his own? It comes up, mostly, because its happening again with the Oelschlagers. Mark was a rising star at Oak Associates, and a fine manager, until something happened and he was gone. He's about to launch two funds that are sort of clones of his earlier charges.
Thanks, as ever,
