I have been examining the Mt Savage to Johnstown movement as well. There is a Garrity and Doran connection in the genealogy of Johnstown for our family. I am happy to share any information I may have. Just send along an email!
I am very anxious to talk to you as I have been researching the Patrick Garrity family tree for at least 25 years! Have visited Mt Savage's Catholic church and cemeteries looking for evidence of Patrick Garrity's death but found 0. Please contact me.
