John Cumiskey was the son of Thomas and Catherine Cumiskey (nee McCartin) of 23 Matthew Street, Bootle.
He died when the Hospital Ship Llandovery Castle was torpedoed off the coast of Ireland on the 27th June 1918.
A report on his death appeared in the Bootle Times on the 19th July 1918.
   Cumiskey, who was a fireman on the ill-fated vessel, was 26 years of age and the eldest son of Mr. and Mrs. Cumiskey, 23, Matthew-street. He was educated at St. Alexander's Schools, and was greatly esteemed both in that parish and in St.Winefride's, with which church he was later connected. About eighteen months ago, he was on a vessel which was torpedoed, and he came home straight out of hospital in Bombay to join the Llandovery Castle. The parents have the sympathy of many friends in the loss of a promising son.

CUMISKEY. - In loving memory of John Cumiskey, elder son of Thomas and Catherine Cumiskey, 23, Matthew-street, Bootle, lost on H.M. Hospital Ship, Llandovery Castle. - R.I.P.
In a sailor's grave our dear one lies.
Not one of us near him to wish him goodbye;
But the angels in heaven are guarding his soul,
Till we meet him again at the call of the roll.
