Humphreys owned various buisness including aerated water manufacturing plants in Canton-China and Hong Kong in the 1870s to 1900s. There is also a person named John D. Humphrey. If you are interested in their history, I have plenty of interesting information and old photographs spanning over 150 years. My father was an employee at one of his businessess. Anyone interested is most welcome. Due to too many junk mail I may miss your email. Please write Watsons/Humphreys as your subject. Thank you.
