RE: John W McFillen I am not related to John W. McFillen. I am writing a series of articles about women who were in the Ohio State Penitentiary between 1885 and 1910. His granddaughter, who is buried in the same cemetery, was in the penitentiary during this time period for killing her lover.
I can tell you what little I do know about the family. In 1860, John and his wife and children lived in Wayne County, Ohio. John's son, Oliver, by 1880 was living in De Kalb County, Indiana. Oliver and his family then moved back and forth between Holmes County, Ohio, and De Kalb County, Indiana. Oliver's daughter, Martha May McFillen, shot and killed George Koechle at Sandusky, Ohio, during October 1898. She was pardoned and released from prison in December 1905. She went home to live with her parents in De Kalb County, and committed suicide during August 1908.
I don't know anything further that is relevant to John W. McFillen. I do have a little more information about his son Oliver's family. If you want that, let me know. However, I am guessing that if this is a 4th marriage, information about children and grandchildren will not be of much use.
