Hi most of this has been sorted nicely for you. Holmfirth is particularly interesting because of several devastating floods in the Holme valley, by far thw worst was in 1852
The 1852 flood occurred when the embankment of the Bilberry reservoir collapsed, releasing 86 million gallons of water down the River Holme. It caused 81 deaths and a large amount of damage to property in the valley leaving many homeless and without work. The buildings and structures destroyed included four mills, ten dye houses, three drying stoves, 27 cottages, seven tradesmen’s houses, seven shops, seven bridges crossing the River Holme, ten warehouses, eight barns and stables.
The collapse occurred at about 1.00am on the 5 February 1852 following a period of heavy rain. The story of the flood made the front page of the London Standard newspaper.
You will find many other references to it. My wife and I made a special stuy of the disaster a few years ago
Amongst the donations to the relief fund is one from a Charles Lockwood for £10 and 2/6d from a George Mellor of Kirkburton. Godfrey Mellor and Thomas Mellor both donated £20. I have a full list of all who died and neither family name is on the list Thought this would be of interest
