If I have you pegged - you and my wife are 4th cousins. Your line should be yourself, Harold Raymond Nettleship, Orville Raymond Nettleship, William Owen Nettleship, George Wheatland Nettleship, William W. Nettleship and lastly Edward Nettleship your Gr-Gr-Gr-Gr Grandfather.
My wife is descended from William Rapier Nettleship the brother of George Wheatland Nettleship. Her line is Patricia (Johnson) Banks, Margaret Caroline (Rayner) Johnson, Marie Caroline (Nettleship) Rayner, Franklin Nettleship, William Rapier Nettleship, William W. Nettleship and Edward Nettleship.
Unfortunately, there aren't any Nettleships in Piqua. But, we live in Xenia just 15 miles from Dayton. I think there are still some in Columbus. In the Spring we plan on a day trip to Piqua to search out the Nettleship headstones in the Forest Hill Cemetery in Piqua.
I have 453 descendants in my database for Edward Nettleship so how deep do you wish to dive into genealogy? I am willing to share what I have.
