Above is a link to the American Chesapeake Club "Pups for Sale" web page. The closest to KY I see is NC. Also if you PM me I can give you the number for the ACC rescue chair, and she can tell you what may be available that way.
My deepest sympathies to you for the loss of your Lab. I had my Chesapeakes out hunting just over three weeks ago, and just as I was loading them in the car my young female decided to chase a passing car. It clipped her on the right hind leg. Luckily it did not kill her or break any bones, but it did a lot of soft tissue damage to her foot. At over $1500 in vet bills and weeks more to go before the wounds are healed I hope she learned her lesson.
If I hear of a pup available I'll let you know.
