He was the eldest surviving son of Patrick Lynch of Lydican Castle in Claregalway Ireland, and Rosa de Galaya de la Camera.

Descendants Justo's fortune was one of the largest in the region, properties, and business he received from his family, in addition, he married the Spanish heiress Ana Bernardo Roo (d.1836), who doubled the extent and value of his properties; consequently, his sons enjoyed a wealthy life like no other Irish immigrants in the region.
