I got the names of Maria's parents from the backs of old family photos.
Yes Thomas Ratchford was who Maria Dolan married. I just sent an email to a Catholic Church in Faribault, Minnesota and hopefully that can help steer me in the right direction.
The 1880 Census records show her parents were from Ireland. Everything I have found says that as of right now.
Thanks for your help & patience!
Trying to attach the back of the photo and the marriage stuff...hope it works
