The catalogue of material donated by Randal Sadleir, the son of former Deputy Ulster King of Arms, Thomas Ulick Sadleir is available at Manuscript Collection List GO 1000. Much of this collection relates to T.U. Sadleir's time at the Office of Arms from the 1910s to the 1940s, and offers an interesting insight into the operation of the last office to pass from British control to the Irish state.
