Steigler's - Stephanie skated with John Zimmerman. Younger siblings Johnny and Tiffany skated pairs, as well. Eventually, Johnny retired. Tiffani tried other partners and even moved to ice dance.
I guess Gracie and Carly Gold could be another example of this sibling "gene." Although Gracie is the stronger skater and "famous" for her name, Carly has more than shown her stuff at regional and sectional competitions before, almost qualifying for US Nationals last season.
the Baldwin brothers seemed to have more money than gene.
