I have visited the McClung collection and have seen this Cornelius. I have been unable to find further information on him to determine whether or not he is or isn't the Cornelius I am looking for. If he is, then he might have been my ggg grandmother Mary Ann Cody's husband but he would not be the father of her youngest daughter Emma (my gg grandmother). She was born in 1868 and this Cornelius died in 1862. I wish I could find further biographical info. on this Cornelius. Thanks for your help.
