Is it possible she took her maiden name back?
This is what I found, you will have to decide which one is her, I have included her social security numbers, because it may be possible to find out where she was born through it from the social security department. In order to receive your ssn#, you have to get a certified letter or birth certificate indicating where you were born. Also, you may know where she went by knowing where her relatives lived. This is why I included the residences. It's a list of Catherine McDonell's. If you know her birthdate, you may be able to pick her out. Don't dismiss the spelling of McDonell/MacDonell, I have noticed McDonell's don't know how to spell their names. I'm one of them. Well, Good luck, if you want, I can search through the King's. Also, if she isn't here, she may be still living. I'm sorry about your loss.
