Hi, John O. Blowers's wife was Sylvinia Chadsey (from Ontario Canada). She died in Delaware, OH. I have the date but not in my memory--about 1856 I think. Her brother James wrote a Chadsey Family History which is available in some libraries.
John O and Sylvinia were my great-great grandparents. I was born in the house John O built in Liberty Twp.
