It's great fun for having a nosey at TB pedigrees etc.
There are a few Pierres on there, but if you search for Pierre, select the one you want and click on progency report you get a list of all known offspring. If it's the first one then there are loads! Once you've got siblings names have a google and see if you can find them
No didn't know about that site, only ever looked on racing post and found he did have a couple of decent ones, mine just didn't pick the good genes up! Ill have a look at site you mentioned, thankyou. If anyone one else does happen to own one, would love to know what they are like.
