Hello
I have looked up the Glasgow 1901 census and found the following entry.
Listed are Henry Lauffer as Head. He is given as importer of cigars and cigarettes, owner (equivalent of self-employed today), aged 66. Place of birth is Germany (no town mentioned) and he is noted as still being a German subject - as are all members of the family!
Frances, his wife is 48.
Son Henry, 23 is a packer of muslin goods, worker.
Son Adolphus, 20 is a joiner, worker.
They were living at 299 Swanston Street in Bridgeton, Glasgow.
I hope this helps you further.
Regards
