Roy asked what was the attainder of the Hamiltons in the 17th century. It depends on which Hamiltons you are cocerned with : 1. Sir James Hamilton (1575-1652) was granted the Abercorn - Baronscourt estate (Manor of Dunnalong) in Co. Tyrone in 1610, as well as land in several other counties. During the Irish Rebellion of 1640, he surported the Irish Sir Phelim O'Neill of Kinnard (Aghaloo Parish) against the British. Hamilton lost his land grants in Co. Tyrone and elsewhere as a result, but they were gained back by his son, Sir James Hamilton (1604-c1670). 2. Captain William Hamilton was granted the Manor at Kinnard, Aghaloo Parish, Co. Tyrone, which had been taken away from Sir Phelim O'Neill, before he was executed in August 1653. Before the 1640 Rebellion-Cromwellian War, Captain William Hamilton had been a tenant on the Winfield Estate (Manor of Benburb), Co. Tyrone. Captain William Hamilton was the grandson of William Hamilton who had come from Scotland in 1616, settling at Ballyfattion (Sion's Mills), Co. Tyrone. According to Mona Wylie, "St John's Church, Caledon, Parish of Aghaloo: A Brief History," (131-42) in Duiche Neill: Journal of the O'Neill Country Historical Society, Vol. 3, 1988: Captian Hamilton was a '1649er.' This would mean that at the outset of the Rebellion of 1640, Captain William Hamilton fought on the side of Sir Phelim O'Neill, later supporting the Royalists forces of Charles I. When Cromwell's army arrived in Ireland in 1649, 'the 1649ers' are soldiers who switched sides to support Cromwell. Most of such Captains were granted land in Ireland at the end of the war in 1652-53 by a grateful Cromwell. But I have seen no mention of Captain William Hamilton being granted land in that period. According to Rev. J. M. Batchelor, "Tynan Parish, Armagh, Burials and Baptisms, 1683-1723," in Duiche Neill, Vol 15, 2006 (100-101): Captain William Hamilton was a Royalist supporter of Charles II, and as a consequence Charles II granted the former Estate of Sir Phelim O'Neill, at Kinnard (Caledon), Aghaloo Parish, Co. Tyrone. While those two accounts might appear conflicting, it was not uncommon for people to switch sides repeatedly, depending on which way the wind was blowing. In any case, Captian Hamilton was not attainted for anything. I'm not aware of these families involvement in the Williamite War. Gwen Barry gwenb@eastlink.ca
