President's Chain

The County Donegal Historical Society received a Presidential Chain of office at the County House, Lifford on the 11th September 1971. The presentation was made by Mr. E. W. R. Cookman, the immediate past President, in the same room where the inaugural meeting of the Society was held on 20th December 1946. At the function, the President, Dr. J. D. Simms, was invested with the chain of office. Past Presidents or their relatives subscribed to the gift to commemorate the Silver Jubilee Year.
The silver gilt badge has the name of the Society in Irish and English. The centre piece is quartered with illustrations representing important periods in the history of the county. The stone fort of Grianan Ailigh on its elevated site recalls the pre-Christian era. There are numerous reminders of this age scattered throughout the county as court cairns, portal dolmens and other Celtic forts but the Grianan is the most notable example. The early Christian period and its missionary activity of St. Columba and others is represented by a monk seated at a writing desk. Below is the motto "Peregrinari pro Christo" - to be a traveller for Christ. The O'Donnell arms, which is primarily an arm with a cross held in the hand, was selected for the centuries when this Gaelic clan held sway over the most of the county. The last quarter depicts the well-preserved ruin of Donegal Castle on the banks of the River Eske, for the planters of the Ulster Plantation. The picturesque castle was rebuilt in 1610 and incorporated a section of the O'Donnell Castle.
The chain has gilded links with a separate link for each of the seventeen Presidents from 1946-70. This number will increase as the names of new Presidents are added. The chain was made by Weir & Sons, Dublin and the Society has taken out an insurance policy for it. E. W. R. Cookman 1971
