JC registration/pedigree help?

[Mike A]

Not to hi-jack the thread, my wife had a retired horse she fox hunted with,

Horses name was Grace's Dare, any help with pedigree, PPs, or other would be great

Guessing she raced at GSP or other NJ, Del, PA or MD tracks in the early 70s

Some I have traced to errors by the track photog. But here's 3 from a RKM race in 1968:

Wace
Dooberg's Dare
Chere Charlene

Oh and I'm not even looking for charts or results...basically I'm seeing all of these old win pics posted and I'm curious mostly about pedigree.
