Lord Castleton’s Regiment of Foot was raised in 1689 by Sir George Saunderson of Saxby, Lincolnshire. It took its name from Saunderson’s Irish title, Viscount Castleton. Saunderson was appointed 8 March 1689 and his regiment first mustered at York in June 1689. A detailed history of the regiment can be found on the Lancashire Infantry Museum website, according to which the regiment first saw action in Flanders in 1692 during the Nine Years’ War. It is seen as the precursor of the current Duke of Lancaster’s Regiment, by way of several amalgamations, including a 19th-century amalgamation to form the East Lancashire Regiment and the 21st-century amalgamation of the three North West England infantry regiments, including the Queen’s Lancashire Regiment. 
A battalion of the regiment under the command of Col Thomas Fairfax was stationed in Preston in July 1689, according to the diarists Thomas Bellingham and Lawrence Rawstorne, as their following entries show:
‘Ye 6th. A fayr day. Mr Barton came here. I went out to see a battalion of ye Ld Castleton’s regiment exercise. I was wth Mr Barton and others pretty late.’ (Bellingham)
‘9 went to Hutton Grange & returnd to Penwortham dyned there & ‘ith’ evening at Ancor wth Coll fairfax Capt. Sanderson Capt Wichcoat & others’. (Rawstorne)
‘Ye 9th. A very hott day. Mr. Barton and I were treated att Mr. Hodgkinson’s, and were late att ye anchor wth Coll Fairfax and other officers of Lord Castleton’s regiment.’ (Bellingham)
‘i0 went to Bowles to Swanseys dined there the officers above menioed & Mr Mayor & diverse others. Mr ffleetwd &c was after at Ancor wth theim.’ (Rawstorne)
‘ Ye 10th. A hott day. Mr. Hodgkinson, Mr. Barton, and I went to Ormskirke to meete Mr. Roper. Din’d there and went to waite on Coll Fairfax att our returne.’ (Bellingham)
Col Fairfax, who had commanded a regiment of foot in Ireland before the Revolution, was appointed at the same time as Viscount Castleton. Castleton’s regiment did not see service in Ireland with William III.  Capt Wichcoat would be George Whichcoat.  Capt Sanderson would probably be Captain Charles Saunderson, possibly a relation of Viscount Castleton.
