I live in Kentucky, and am also considering getting a Jersey for my own milk production. There are alot of private breeders in Kentucky that I have found on Craigslist and Facebook buy/sell/trade pages. I'm still in the planning & research process and will not be purchasing one until well into next Spring, so I don't have names for you but of most I have seen on Craigslist are from show Jerseys for 4H and all their animals are required to have vaccines, I would consider them reputable, responsible cattle owners but always look at their paperwork to be sure
