Might the reference section of the local library be able to help? If you give them the full name, they may possibly be able to provide the appropriate address from electoral registers pre or post war?
If you are just seeking likely addresses, you could try the Lancashire online Parish Clerks site, and then click on Burnley ... then go down the registers list, right to the bottom, where there is the local cemetery records.
If you type in the surname(s) you are after, then I think there's a facility to find the others in the same grave - and in many instances until a couple of decades back, the address is given where the person died. Could that be of any help?
