Sorry Obadiah, I have no idea if or where there would be records kept.
But...prior to the 1850's it took an act of parliment to obtain a divorce, so it was very costly and very few people divorced. Therefore, I imagine it would have been a noteworthy occurance and might be in the local area papers. Newspapers should be archived, try a Google search for divorce in Tewkesbury or Upton.
Otherwise, wait for a more knowledgeable person than I.

Leonie.
