The family first settled in England but later moved to Ireland where their principal seat was at Ballyheigue where the head of the family was known as "The Cantillon". Like so many of their neighbours they lost their estates, as a result of their loyalty to the Catholic faith and their supporting of the Catholic Confederation, and later their support of the Jacobile King James II. Indeed a Cantillon was Chaplin to Sarsfield's Regiment.

There has always been very strong ties between the Cantlon or Cantillon family of Ireland and France.
