Seeking help identifying an American studio potter signed “John” (1996)

Hi everyone! I am trying to identify the specific potter behind this lovely matching set.

Details: It features wheel-thrown stoneware with a dipped cobalt/periwinkle blue rim and hand-painted violet/wildflower details.

The Mark: The bottom has an incised hand-written signature that reads “John 1996” on a raw clay foot.

Provenance: The mug was originally purchased in Fernandina Beach, Florida at the Isle of Eight Flags Shrimp Festival back in the 90s. My mom says the potter said he also sold pottery in a shop/gallery across from a toy store in downtown fernandina down the street from Brett’s Restaurant.

I also recently tracked down a matching 6" pitcher with the exact same design and signature. I'm hoping to find his full name or studio name so I can search for more matching mugs to fill out a set. Does anyone recognize this signature style or remember this specific vendor from the 90s Southeast festival circuit? My mom bought the mug in the 90s and it has been a beloved piece in my family for decades. I would love to buy my mom another one or find more pieces. Thank you!
