Hi Goldlabel and davidfromgalloway & all,
The Charles Moore I found in the 1901 census, is listed as an Aerated Water Manufacturer at Brownside Road, Cambuslang born in Glasgow in 1867, his wife is listed as Agnes, born 1869 Glasgow. The children are Agnes b 1888, Annie b 1890, Maggie b 1892, Helen b 1894, John b 1895 & Charles b 1897. There was a servant called Martha Gardner aged 16. All children born in Glasgow.
This must be a different family, unless it was the young Charles b 1897, he may have had a younger brother born after the 1901 census called George.
CMS Jr mentions that his Charles Moore married his grandfather's sister. Would need to prove who sister was and work backwards presumably to get correct Charles Moore.
