This database is based on a transcript of an Exchequer Bill of 28 April 1741 involving Robert Blackwood of Ballyleedy [Ballyleidy, Bangor parish], Co. Down, esquire. It was copied by Tenison Groves and may be found in his collection of genealogical notes in the Public Record Office of Northern Ireland (T/808/15009).
