I am trying to find information on my grandfather Charles Franklin Welker Sr. "Frank". I found a photo of his father Albert in 1911 . I am looking for any information for coal mines located in irvona/coalport. I looked on the patheoldminer.com site and couldnt find any useful information (even emailed the owner and sent the photo of my great pap Albert Welker for him to add to his information). I know my grandfather was a coal truck driver for Benjamin coal co and Byers coal co. and my father says his tags say no 9 so i assume its mine no 9. My great grandfather worked at the Irvona coal and coke co mine no 3. My father says that pap worked at Sunshine mine no 9. Any information would be greatly appreciated! thanks!
