After I found the first one of those subdomains, I then found an obituary that gave me great new info about my gg grandfather. I knew I needed to find more of those A-P subdomains that had old newspapers, and post the link in each appropriate ancestry county message board, because I knew those subdomains were not well known among us genealogy buffs, and I know how sought after old obituaries are. Plus other newspaper stories about people while they were living.
So far I have found 110 subdomains that had good, old newspapers. There are more subdomains, but they didn't have usable items for genealogy buffs.
