When Joseph Hetherington died in 1873, there was an extra provision for his daughter Mary to have a home and place for herself and her daughter, Mary Clementine Kenny, with her brother Alvy so long as she lived apart from her husband John Kenny. Since Mary Hetherington and John Kenny had four more children evidently their separation was only temporary.
The names and birthdates of their children are unknown to me thus far. If you have information that you are willing to share with me it would be greatly appreciated.
