You never know.
Even through Heaven Rocks (Rocknroll Heaven from Mendelico) brought a good price when sold at the APG sale...it's family has only a sprinkling of winners:

From the taproot mare Old Kate to Mendelico, there are 11 less than noteworthy mares, including the embarassingly named Dustcan and her daughter Can Opener.

You never know where the good ones come from !
