Anne, daughter of 1st Viscount Dungannon married the 1st Earl of Mornington in 1759. Annadale Hall where she resided for a time is said to have been called after her. She was the mother of the future Duke of Wellington who lived there as a boy. The Massarene family of Antrim stayed in Annadale Hall in 1814 whilst Antrim Castle was undergoing extensive repairs. Annadale Avenue was formed by William Hartley who along with J C Greer had bought 90 acres in 1868. Annadale Hall was burned down on 17 January 1921. (A very detailed and fascinating background to Annadale Hall can be found on Dennis Kennedy’s website here: https://bit.ly/2PZBSBh)
