The Stewart Family, formerly of Tyrcallen, Co. Donegal, trace their ancestry from Henry Stewart (1743-1840), a younger brother of James Stewart (1741-1821) of Killymoon Castle, Cookstown, Co. Tyrone. Born in 1743, Henry was educated at Trinity College Dublin receiving a BA in 1768 and was admitted to both the English and Irish Bars (1773). He was also sometime MP for Longford Borough, but is best remembered as a professional Land Agent working in partnership with Graves Chamney Swan as Stewart & Swan, firstly in Clare Street and then at 6 Leinster Street, Dublin. In 1793, he married Elizabeth Packenham/Pakenham, daughter of Edward Michael Pakenham, 2nd Lord Longford, and sister of Catherine, Duchess of Wellington. With the assistance of George Whitelocke of Wokingham, Berkshire, Henry purchased the Tyrcallen estate from Rev. Oliver McCausland in 1789; where his family remained until it was sold c. 1845-49 following his death in 1840. The family papers were passed down through successive generations of the family until their deposition at PRONI in 1978 by Gerard Pakenham Stewart of New Zealand, who carried out much research into the family’s history. Mr Stewart died in 1998. \n\nSources:\n<a href="http://www.maitland.anthony.net/stewart1.htm" target="new_window">http://www.maitland.anthony.net/stewart1.htm</a>;\n\n<a href="http://proni.nics.gov.uk/records/private/stew_tyr.htm" target="new_window">http://proni.nics.gov.uk/records/private/stew_tyr.htm</a>.
