Thank you so much for the great tip! Joseph O'Toole, my Great-grandfather was born on June 17, 1873. His sister Mary was born about 1875. That would make her 23 at the time Mary O'Toole married Mr. Edge.
Unfortunately, I have no information on Michael O'Toole except that he ran away to join the Union soldiers when he was too young to enlist and eventually fought in the Civil War at the Battle of Gettysburg.
Any additional tips to track down descendants of Mary Edge's to try and discover if she is one of my O'Toole's would be appreciated.
Thanks, Susan Cary
