But Barry is the brightest star in his family's racing production line as his performance at this year's Cheltenham Festival and Grand National showed.
Five winners at Cheltenham, equalling the best return at the meeting, helped gain him exposure this side of the Irish Sea.
And he secured an international reputation when riding Monty's Pass to a famous victory in the National at Aintree.
In Ireland, such riding feats have been commonplace, and Geraghty's talents were less of a secret.
After a background in pony racing, he began his apprenticeship with Noel Meade and rode his first winner in January 1997.
Three years later he was well on the way to becoming Irish champion jockey for the first time to cap a meteoric rise to the top.
He has since finished runner-up twice, but is pushing Paul Carberry hard to reclaim the ultimate honour this season.
Having started out riding for Meade, Geraghty now rides mainly for Jessica Harrington.
In partnership with the Irish trainer's Moscow Flyer he has enjoyed two notable wins at the Cheltenham Festival, the second of which came in this year's Queen Mother Champion Chase.
Last year at the National he was unseated by Alexander Banquet at Becher's Brook.
And the close of his season was further disrupted by a viral illness.
But he has come out this season in fighting form as his Cheltenham return highlights.
