Two hundred passengers are lost in the shipwrecks of the brigs Trevor and Nonpareil on October 20, 1775. Among the casualties are The Hononorable Major Francis Caulfield, Member of Parliament (MP) for Charlemont, his wife, and daughters. Also lost is John French, Member for Roscommon County.

On Thursday, October 19, 1775, the brig Trevor, with Captain William Totty at the helm, and the brig Nonpareil, with Capatin Samuel Davies, sail from Parkgate for Dublin. That evening, as the vessels are near Holyhead, the wind shifts about from the south southwest to the west, and so violent a hurricane arises that they cannot carry any sail, but are obliged to lie to, and drive before the wind. In this situation, the Trevor drives upon the banks near the Lancashire shore and is totally lost.

Everyone on board perishes, except Samuel Fairclough, a mariner, who miraculously saves his life by leaping aboard another vessel named the Charming Molly, under Captain Joseph Holloway, which is transporting coal from Chester to Newry. The Charming Molly accidentally runs afoul of the Trevor and carries away the Trevor‘s foretopmast and, at the instant the two vessels come together, Fairclough makes his leap. He was the only survivor of the 30 to 40 passengers and crew aboard the Trevor.

Captain Holloway states that his vessel and the Trevor came together at some distance from the coast. They parted at the time Fairclough jumped across, and the Trevor subsequently went to pieces. A great many chests, boxes, some of which are broken, and quantities of East India goods are strewn along the shore, all wet with salt water. These items are in the custody of Mrs. Hesketh, Lady of the Manor of this coast, secured by Mr. Standen of Rossall Hall. The East India goods had arrived by land from London. The cargo and coins aboard the Trevor are estimated to be worth £15,000.

The Charming Mary runs ashore at Blackpool with most of her sails carried away, but otherwise with little damage.

The Nonpareil is lost in the storm between Parkgate and Dublin, driven on shore near Hoyle-sands and lost. There are no survivors. The wife of Captain Davies states that her husband sailed from Parkgate with very low spirits as he did not like the appearance of the weather. He is pressured to put to sea, which he does, and is turned back twice, but gets off on the third attempt, and is never seen again.

Between them, the Trevor and the Nonpareil reportedly carry nearly 200 passengers, the majority being on the Nonpareil. They carry cargo valued at £15,000.

On Tuesday evening, October 24, the Collector of the port of Chester receives the melancholy account of the loss of the Trevor by a letter from the Collector of Poulton, in Lancashire. This is immediately communicated to the Merchants, who are concerned in shipping the cargo, and they set out as soon as possible to give assistance and to secure each part of the cargo as might come ashore.

The merchants from Chester reach Poulton late on Wednesday night, October 25. The following morning, they set out along the shore from Blackpool, where the Charming Mary is stranded. The greatest part of the hull of the Trevor lay scattered along the shore at a great distance. On their arrival at Rossall Hall, about six miles from Blackpool, they have the satisfaction to find that Mr. Standen, who is Steward of the Manor of Bold Fleetwood Hesketh, now a minor and son to the deceased Fleetwood Hesketh, on whose estate the wreck is taken up, has taken all possible care of everything that can be saved from plunderers.
