Thanks again to everyone... so much information. I knew that several streets were named after Dixon's ironworks, namely Gartuck street, Carfin street and Calder street. I knew that Belleisle street was named after Dixons residence in Ayrshire. I knew that Allison street was named after Sir Archibald Allison and predates the other streets above that lead off it. I've seen reference to the Ailleen Smart book before and its nice to learn that it can be downloaded but her assertion that Daisy and Annette were William Smith Dixon's daughters are at odds with this reference :-
http://www.glasgowwestaddress.co.uk/100_Glasgow_Men/Dixon_William.htm which states of Dixon:- He died in London in June, 1880, having married in 1851 Catherine Anne, daughter of David Napier, merchant, of Singapore, by whom he had no children, and who died in 1884
