I just happened to see the name Walworth in connection with Addison. There are Walworths in the Oak Grove Cemetery in Manchester (Washtenaw Co) too. Let me know if I can help. I am the volunteer in the Manchester Historical Room at the Manchester District Library , we have the Manchester Enterprise on microfilm back to its beginning in Oct 1867. I also have a lot of cemetery records for Oak Grove going back to 1856 when Oak Grove was established. Karen Jenter Manchester
