For information on those who were involved in the siege of Derry in 1689 and events during the Williamite War in general, the best single source is W.R. Young, Fighters of Derry: Their Deeds and Descendents, Being a Chronicle of Events in Ireland During the Revolutionary Period, 1688-91 (London, 1932).
Young compiled biographical sketches for hundreds of those who took part in the conflict, both Jacobites and Williamites. This book contains a fascinating overview of Irish society in the late 17th century, particularly the settler community in northwest Ulster. This database contains the index to this volume, displaying the page number reference for each record.
