Composer, born in Liège. He served as a royal choirboy in Madrid from 1586 to 1593 before joining the Flemish chapel, where he became maestro de capilla (1598-1634). He was ordained a priest in 1609 and served as chaplain to Philip III in 1605, and also held a nonresidential post of chaplain to the court of John IV of Portugal from 1644. Romero was highly regarded in his time as a composer of sacred and secular vocal music; many of his works are no longer extant.<
