This stained glass window and accompanying plaque are in the Church of St Thomas the Apostle, Ashton-in-Makerfield, Lancashire (now Greater Manchester). The theme of the windows is The Transfiguration of our Lord.

Perhaps someone more conversant with names on records might be able to fill in details of Gerrard and Shaw?
Additionally, there's 8890 Trooper Richard Williams, 32nd Company Imperial Yeomanry, who was invalided home after contracting enteric fever at Kimberley, and died in a UK hospital on 27th November 1901. His death here meant he wasn't eligible for inclusion in the above roll of honour.
Four of the names included in the casualties to the Yeomanry, reported in the engagement at Kheis, are those of St. Helens men - viz., Private J. Fairclough, of Peasley Cross, killed ; Private W. Swire, plumber, of George-street, wounded ; Private F. J. Roberts, Vincent-street, wounded ; and Private Dancer, wounded.

Trooper J. P. Fairclough was one of the finest-looking members of the "B" troop of Lancashire Hussars. Although he would not have attained his 23rd year until the 23rd of this month, he was 5 feet 10 inches in height, and well built. He resided with his parents in Peasley Cross-lane, and in civil life was employed at the Whitecross Colliery. Deceased had only been in troop two years, but was a very efficient member, and all who knew him regret his death at so early an age. His parents received word from the War Office on Friday that their son had been killed, and naturally the news has been the source of great grief to them. Deceased has a brother in the same troop, who fortunately came through the action without injury.
It will be remembered that some weeks ago the St. Helens Yeomanry were in action at Kheis, in Cape Colony, and several were wounded. The sad intelligence has reached St. Helens that it has been found necessary to amputate Trooper Roberts' leg, in consequence of a wound. The sympathy of all St. Helens people will be extended to his parents.
