I just started looking a few minutes ago - but a lot of the ones I looked at haven't been much. Secretariat's dam got drubbed in her only race - and John Henry's dam was getting slapped about at River Downs.
Here are forms of a few:
* Dam of Dr. Fager starting for a claiming tag for the 1st time:
* Dam of Seattle Slew was beaten a couple times for a maiden claiming tag:
* Dam of Man O' War beat double digit lengths in a maiden race at some track I've never heard of:
* Dam of Native Dancer was a respectable racer - but no star:
