Somebody out there want to write a book? Or maybe just start a list. I've wished for a list, too. Every time I'm back in Hancock County, I've threatened to search the newspapers and start one, but I never seem to have time. I can give a dates for a couple of photographers from pictures that I have identified of my own family.. Zays was in Findlay in 1871 and Buck was in McComb in 1896 and 1900. Also Henderson (sp?) in McComb in 1900. All give or take a couple of years. There is also apparently a good web site at <http://www.city-gallery.com/> regarding the dating of several types of photographs from their mountings, etc.. I have not visited the site, only seen data taken from that site - Leah in Texas
