Hello, the son of Samuel Walker and Rose McGhee (Harry) is actually Henry Walker, born about 1892. He married Maria Christie on 4 April 1936 at 5 Ann Street, Greenock. Sadly, Maria died of tuberculosis two months later on 30 June 1936 at the Combination Hospital, Port Glasgow. Samuel Walker was born in Glasgow in 1825 and Rose was born in Edinburgh in 1870. They are on the 1911 census of England, living at Woolwich, London. Photos would be great, you can post them as an attachment (button below). I have more information on Maria Christie if you want it. Do you have the marriage date and place for Samuel and Rose? cheers, Mary.
