John - this may well be a connection.The Samuel i mentioned is my Gt Gt Grandfather.He was "a nut and bolt manufacturer in the town (AUL), who lived for many years at Moss Cottage" according to his son's obituary.I have some sketchy letters which suggest that this Samuel's father was an Edward, and that his father in turn was Samuel. Maybe this is the Samuel for whom you have records?
Also i have found some information from the 1821 "Pigot's directory" (whatever that is?) which lists Samuel Garside "smith and ironmonger" of Hash Hall.According to my (now deceased) information source "he calls himself a 'whitesmith'". Seems to match with your info!From the same source i think he had son's called Edward and Joseph.
Out of interest (and in case it is of interest to other, i have the following information from the Ashton Trade Directory of 1841:
Benjamin Garside - portrait painter, Welbech St Edward Garside - Ironmonger Hugh Garside - Shopkeeper, Scotland St. Joseph Garside - Ironmonger, 175 Manchester Rd Joshua Garside - Highways Surveyor, Catherine St Margaret Garside - Blacksmith, 181 Manchester Rd (i think this is my relation too) Robert Garside - Hairdresser, Stamford St Samuel Garside - Shopkeeper, Delamere St Miss Sarah Garside - 144 Manchester Rd Sarah Garside - "Horse and Jockey" Wellington Rd Henry Garside - Attorney, 51 Stamford St Johnathan Garside - Grocer, Margaret St.
I would be very grateful if you could search out your reference to Samuel.Regards, James.
