Company Names, addresses, dates¹:

(832 Gibbon St. & 600 S. Alfred St. probably refer to the same building, at the corner of Gibbon & Alfred Streets)

Notes:
A Washington Post article on February 27, 1895 said that Lewis Young sold his pop & soda water establishment to James McCuen for $1500. An earlier Post article from April 17, 1894 said that James McCuen's store at the corner of Alfred & Gibbon streets was broken into by theives. And a later Post article from January 6, 1899 said that the Alexandria Bottling Company at the corner of Alfred & Gibbon streets, owned by James McCuen, had a big fire. And a much later Post article from October 8, 1907 referred to James McCuen as a Grocer/Liquor Store owner at the corner of Alfred & Gibbon Streets.
From these and other post articles, as well as the few Alexandria city directories I have access to, I've been able to determine that Lewis Young was a bottler who sold his company to James McCuen (although they must have worked as a team for a while based on bottles that say "McCuen & Young"). At some point, McCuen started using the name "Alexandria Bottling Company", and it lasted until at least 1907.
