Joseph and Mary O'Neal Roach lived about eight miles from Ross in County Wexford in Ireland in about 1847. They had at that time four children, for whom the parents had little hope of a good future there. Joseph was a tenant farmer for an English landlord, as the Irish were not allowed to own land. Despite laws that made it hard for people to leave the situation, they saved, and with cash from an (unauthorized) sale of some prized sheep to a neighboring landlord, they left with their two older children. The younger two (John and Anne) were left behind, one with each grandmother. The family would not be re-united in America for another 14 years or so.
