What we do know with confidence is where she's trained. G M Lyons operates out of Dunsany in County Meath, and the yard has been in sharp form this season — 49 winners already, which is the kind of number that tells you this is not a stable going through the motions. When a trainer of that calibre sends a first-time runner to the track, it tends to mean the horse has done enough at home to deserve the outing. Yards with that volume of winners don't waste entries.
Beyond that, the honest answer is there's nothing more to go on yet. My Girl Grace is an unknown quantity — and in racing, that's genuinely exciting. The debut is the one moment when a horse can surprise everyone, including the people who bred and trained her.
