Pedigree Query

Thanks so much! I was just curious because I thought maybe it was my horse. I know nothing of his past or breeding. Just that he has definite Thoroughbred breeding. The name and birth year added up. He is not tattooed either- Thanks for the info.

I'm trying to find out information on Nimbus8. I don't know anything about researching pedigrees and when I enter this horse nothing really comes up. What does this mean? How would I be able to find out anything about the horse? Any help would be really appreciated! Thanks!
