"O'Brien" is usually a surname, but here it looks like it's the name of the company that made the product (which was likely named after the founder). Edit: I looked it up, and apparently O'Brien Potatoes/Potatoes O'Brien "is a dish of pan-fried potatoes along with green and red bell peppers. The potatoes and the bell peppers are fried (varying according to taste) and are served hot. It is made with regular potatoes, not sweet ones." https://en.wikipedia.org/wiki/Potatoes_O%27Brien According to the above link, the dish likely comes from Boston or Manhattan. As to the name, Dictionary.com speculates that the name comes from "the conventional association between the Irish and potatoes, O'Brien being taken as a typical Irish surname". http://www.dictionary.com/browse/o-brien-potatoes
