I just found this site by googleing Acme cotton mill. I live in USA but was born in Salford. My maternal grandfather was an engineer at Acme. Also lived at 479 Bolton Rd.,Pendlebury. My mother had a hair salon at same address and grandmother had a little hardware shop. My Mom passed last year and I'm trying to find cemetery where grandmother is buried to place some of Mom's ashes with her. Also since I was little was told about the bombing of factory during WWII. We have a piano with shrapnel from that bombing. My Mom attended Clairemount School, 1928. Any advice where I should start to find correct cemetery.
Thank you in for any help.
