R.P. Cook - Names, addresses, dates:
    R.P. Cook, King Street, Alexandria VA (1855) ^1,2,3

Notes:
I believe this bottle is attributed to Richard Patton Cook (1821-1894)⁴, who had a brother named Garret Albertson Cook (1818-1896)⁵.

Starting in February of 1855, G. A. Cook became the agent for R. P. Cook ¹.
G.A. Cook had just left his partnership with J.M. Roseberry & Co ².
I couldn't find any newspaper references to R.P. Cook's bottling establishment prior to late January of 1855, so it may have started at that time.

2 advertisements that listed "G. A. Cook agent for R. P. Cook" were run in the Alexandria Gazette in 1855.
    The first advertisement ran from January 25 to March 1, 1855. It said that on or after February 1st the subscriber intended to commence bottling Philadelphia Porter, Ale and Cider. It also said he intended to manufacture all kinds of mineral waters such as Sarsaparilla, Lemon & Ginger¹.
    The second advertisement ran from April 16, to May 16, 1855. It said that the subscriber intended to supply superior bottled Porter, Ale and Mineral Waters. It also said that he was opposite his old stand and next door to O'Neal's Hotel on King Street³.

There was one more advertisement in the Alexandria Gazette, which appeared on the July 4th 1855 edition. It touted "summer drinks" bottled by G. A. Cook, and said nothing about "R. P. Cook".⁶

Based on all the newspaper articles I could find, I suspect that Richard Cook put up the money to pay for the bottling establishment, and Garret Cook actually ran it. I also suspect that it didn't last beyond 1855.
