Help Please.... Can anyone tell me if there is a town called Fort Thomas in Ontario, or was this actually military fort called Fort Thomas. Im trying to locate the place where my great grandfather was born. He was born sometime between 1850 and 1856 in Fort Thomas, Ontario, Canada. His name is John James Wheeler Sr. He immigrated to Michigan, USA> His father was Wilford Wheeler who was born in Pennslyvania and his mother was Larsea Gilbert. She was born in Canada
