I would think Jimmy would be from the region, possibly the NYC-NJ-Conn. area. It is obvious that he is some sort of street tough, possibly of poor Irish descent. He seems a throwback to some old-time movie characters, aka 'On The Waterfront'......He has no apparent siblings, no apparent Father in residence, and a Mother who seems bent on marrying old coots for money and dumping Jimmy at whatever place she can find just to be rid of him.....Jimmy appears to be not-so-bright, being easily swayed by the urgings of those around him.....None of the missions or errands that he does involve any good problem solving skills....The lack of a difinitive accent makes it a bit difficult to pin down just where he comes from, however.
