thanks for the identification of these men. We may update the record to include their names.

4th from left is John Joseph (Rip) Egan. Additional information on his life can be found in "More than Merkle" and "You Can't Beat the Hours" by David W Anderson. as well as from a scrapbook in Google Docs and documented in Wikipedia.

Thanks John for finding the full name on Rip Egan. We'll update the record.

You sure that's not "Rodney Dangerfield"?
