Aidan O'Brien
Aidan O'Brien is married to Anne-Marie (née Crowley). Anne-Marie's father, Joe Crowley trained horses at Piltown, County Kilkenny, where his tenure was interrupted in quick succession by his daughter Anne-Marie (Champion National Hunt Trainer during her brief time at the helm), his son-in-law Aidan O'Brien (who took over from his wife in 1993 but moved on to Ballydoyle in 1996) and then another daughter, Frances Crowley (who moved on to train on the Curragh for some years). Joe then renewed his own training licence for some years before retiring.
