Crumpsall Workhouse (Manchester) 1901 Census: RG13/3771/153/33, has the following two Inmates: Thomas Clark, Inmate, Marr, 64 Yrs, Fish Hawker, born: America, Newport (NBS). Guisseppe Sabatina, Inmate, Widr, 66yrs, Soapmaker, worker, born: Italy (NBS). Not entirely sure of the abbreviations: NBS, but think maybe 'Naturalized Born Subject'.
I was wrong. I just looked it up in the explanation of abbreviations for census and it stands for "Naturalized British Subject"
