If you are looking for information on Woodland, the Clark County Geneology Society http://www.ccgs-wa.org/http://www.ccgs-wa.org/ has much more information on Woodland thanthe Cowlitz County Historical Society http://www.cowlitzcounty.org/museum/http://www.cowlitzcounty.org/museum/. At one point in time Cowlitz County was part of Clarke (yes with an "e", old spelling)County, and actually a small part of the City of Woodland is still in Clark County. The Cowlitz County Recorder http://www.cowlitzcounty.org/http://www.cowlitzcounty.org/ does have records in their vault for the Woodland area but you need to dig. If you are looking up land records, Cowlitz County records it's land records by Donation land claim (DLC). You can get a map of the DLC's from the county.
If you want a very interesting and usually sucessful experience, visit the Washington State Archives in Olympia. http://www.secstate.wa.gov/archives/main.htm/http://www.secstate.wa.gov/archives/main.htm/ The staff there are very nice and have early records from Woodland and Cowlitz County. Again you need to spend some time and dig. The Washington State Library in Olympia, http://find-it.wa.gov/http://find-it.wa.gov/ just a few blocks away from the Archives, have microfilm of very old Woodland newspapers.There are a number of newspaper names, they seemed to change the name frequently.Also look up Kalama, Vancouver and Longview newspapers.I have found information in them about the Woodland area and its people. I hope this information can help. There is information about Woodland, you just have to know where to look.
