Thomas Smiley (c. 1660 – 1689) was a Williamite defender during the Siege of Derry.
Family Thomas Smiley was the son of Presbyterian Minister Thomas Smiley (born c. 1630) in Scotland. Minister Smiley moved his family to County Donegal, Ireland about 1670 as part of the Plantation of Ulster.
Thomas Smiley (the son) married his wife Ann (1663-1731) in about 1679, and they had four children; John, Rose, William, and Francis. Rose remained in Ireland, while the three sons set sail for America in the early 1700s.
Origin The Smiley Family originated from Lanarkshire, Scotland; where their surname was Smylie, Smyly or Smaillie, and other versions exist as well. The family name changed to Smiley in Ireland, as family members settled near Derry in the 17th century.
Death
Thomas Smiley died in battle during the Siege of Derry in 1689. As a Williamite defender of the city, he helped to prevent the fall of the city to King James II, which allowed time for the Royal Navy of William III of England to arrive and lift the siege.
Recognition In recognition of Thomas's courage in battle, the Smiley Family was awarded an Armorial Ensign by William Hawkins, Esq., Ulster King of Arms about 1700.
This ensign was confirmed and duly recorded in 1815 by the Crown; through Sir William Betham, Knight Deputy of Ulster, King of Arms.
Key elements of the ensign include: a Chevron (insignia) which denotes military valour, an armoured arm upon the Crest (heraldry) which signifies strength or power, and iron dart heads Pheon indicating defence of Crown property.
