The breeder is James Comley, as with 'Oakmont': “Further on to the right could be seen an excellent display of cut roses from James Comely [sic; should be "Comley"] of Lexington (gardener to Francis B. Hayes), and among them a large number of the new rose, ‘Oakmont’, and ‘Francis B. Hayes’, of which he is the originator, and the stock of which he recently sold to Mr. John N. May.” [Florists’ Exchange, vol. 3, 1890, p. 213] It appears from here and elsewhere that the spelling is "Francis" not "Frances."

Isn't it more likely that the honoree is Charles-Louis Napoléon Bonaparte, later known as Napoléon III?

The quote from Rivers in 1846--the one with the leaves which are nine inches long--the isolated quote here leaves the impression that the rose being described in the quote is 'Céline'; but on reading the whole passage in Rivers, it's clear that the only thing referring to 'Céline' is that those who know 'Céline' will have an idea of the habit of 'Great Western', which latter is the rose with the nine-inch leaves, etc. etc. etc.
