I am not sure if this will be of any help for you but in the 1860 census my g-g-g grandmother (along with her half brother) Mary M. Brock is living with John and Harriett Winn in Perry Township, Muskingum County, Ohio. I have been researching the Brock family for about a year now. I know that I have come across the name Dolphin Winn. For some reason I thought that was John's father. I saw him in a few newspapers articles from the Athens Messenger around May 1878 in regards to the murder of John W. Brock committed by Jefferson Moorehead. The murder took place in Jan. 1876 in Muskingum County Ohio. Jefferson recieved a full pardon from the Gov. of Ohio in 1896.
