Notes:
Michael R. O'Sullivan (1863-1852)⁴ was a grocer and a bottler³.
Martin P. Greene was listed as O'Sullivan's partner in the 1897 & 1899 city directories. Starting in 1900 the residential directories listed O'Sullivan as "O'Sullivan & Co" and Greene as simply "agent". The 1899-1901 directories list O'Sullivan & Co as "grocers & agents for Washington and Pabst Brewing Co's beer and retailers in keg & bottled beer". After 1904, city directories don't mention him as a bottler or liquor seller, only as a grocer.
The address of O'Sullivan's grocery store is sometimes listed as 931 Franlin Street, and sometimes listed as corner of Patrick & Franlin Streets - I assume that was referring to the same address.
