Notes:
I'm assuming all the bottles below with the name "Vaughan" from Richmond are related, but I haven't yet done the research to prove that. The dates and addresses above are from Vernon Grant's book, which only goes up to 1930, and I suspect that "Vaughan & Vaughan", which is on the label of a bottle below, came after 1930.

(more information will be added when I get around to researching this druggist)
