Phantasy, I had a free pedigree lookup on my owner's account so I went ahead and pulled her ancestry from the Jockey Club and added it to the public free database at Pedigree Query. She had a large amount of european breeding, including her sire Four Marks from Great Britain. I also added her breeder and her birthday to the pedigree. I don't have a race record though. If you don't know her racing history and think she did race, I'll pay the couple of bucks if you'd like to know what she did.
The pedigree is here:
Myrtles Girl Horse Pedigree
Hover your mouse over the circle with the letter I in it next to her name to see the additional info.
Kar, I'm not quite sure what you're asking. If you know the horses' names you can try pedigreequery.com to see if they have additional info on how they did or if there were offspring (under Reports --> Progeny), also siblings and sometimes earnings. However, if you're hoping to take a trip down memory lane, I encourage you to check out the Chronicles of the Horse (COTH) Racing board. There is a great mix of young and seasoned racing enthusiasts and professionals who remember many of the great, and not so great but still loveable, horses of yesteryear. Racing - Chronicle Forums
