Having gone through a great number of Cleveland directories, I have found no Gregor living there. I've created a big spreadsheet of Papezes that immigrated or appeared in census records, and have found that Gregor is an unusual Slovenian first name among Papezes. A possibility is that your Gregor settled in Joliet, Illinois. This Gregor immigrated from Srednji Lipovec in 1907, sponsored by his brother Martin. Gregor's birthdate was 7-Mar-1890 and his wife's name was Frances. They lived at 118 Cora in the 1920's and 1930's. As far as I can determine, they had only one son, William Edward. I haven't been following the female lines in my study, so I can't provide a connection to Mary Wolfe. Gregor's brother Martin had many children, some of whose descendents I've been in contact with. I hope this info may provide you a connection.
