An interesting alternative would be the Loomis Gang also known as the "Nine Mile Swamp Gang" that operated out of upstate NY in the 19th century.
http://en.wikipedia.org/wiki/Loomis_GangI know that its a century later than the time period you are interested in. When I worked as an archaeologist in upstate NY it seemed this gang appeared in just about every mid-state county history. They sortied out of their area sometimes traveling on the new fangeled canals and raided throughout the region. In one account I read the gang stabeled their horses in the town church and started raiding pretty much every house in town and then escaped to their swamp retreat probably via the canals. I'm sure that the authorities got no cooperation from the folks along the canal either as they were damn rough with every other house along the way a tavern or a house of ill repute and canal men being having a rep as the roughest of the rough.
