The information is indeed in Stephenson's book "SCOTCH-IRISH MIGRATION TO SOUTH CAROLINA, 1772 (REV. WILLIAM MARTIN AND HIS FIVE SHIPLOADS OF SETTLERS". Thomas McDill, John Peden and James Peden were among the passengers of the snow (small sailing ship) THE JAMES AND MARY which departed from Larne, Ireland and arrived in Charleston, SC on Oct. 18, 1772 after a voyage of seven weeks and one day. The unfortunate passengers had to stay aboard ship in Charleston harbor until Dec. 1, 1772 due to small-pox; they could only go to a quarantine house on Sullivan's Island on occasion. Rev. Martin brought over 1,000 Covenanter Presbyterians with him to South Carolina on the five ships. As stated above the McDills and Pedens arrived on the JAMES AND MARY; the other four ships were the LORD DUNLUCE; HOPEWELL; PENNSYLVANIA FARMER; and the FREEMASON.
