I thought that for anyone who has a family story , document of a birth, marriage, death, homestead, etc relating to Klamath County may find this of interest. The original county seat, Trinidad, was an important depot for miners supplies. Klamath County has the distinction of being the only California county that was "operational" and then was completely disbanded as a political unit. Klamath County was located in the upper left corner of the state and its lands now comprise portions of Del Norte, Siskiyou, Humboldt, and Trinity. ( I do hope I have interpreted the maps correctly and if this is wrong please correct this post) Although other California counties were created by law,(prior posts on a couple-Washoe and Pautah) were never organized, no other county that had been organized has been completely dissolved as a policical unit. Klamath County was created April 25, 1851 and dissolved under an act passed March 28, 1874. (Coy) Here are some communities that once had Klamath County addresses. I have taken this information from the old California Post Offices site. You can see how communities were changed to different counties as the result of boundary changes and new counties being organized. More details on how to read the information below can be found at the site: http://pbbooks.com/caindex.htm Albeeville , Klamath Bald Hills 67-74 , Klamath Beckwith/Beckworth/Beckwourth , Plumas Bed Rock, Klamath Black Bear 69-74 , Klamath " " /Blackbear 74-open , Siskiyou Cottage Grove 57-72 , Klamath " " 75-98 , Siskiyou Crescent City 53-57 ,Klamath " 57-open , Del Norte Elk Camp , Klamath Forks of Salmon 58-74 ,Klamath " " " 74-open , Siskiyou Hoopa Valley 61-74 ,Klamath " " 74-95 , Humboldt Klamath 66-72 , Siskiyou " 87-15 , Humboldt " 27-open , Del Norte Klamath Mill , Siskiyou Klamathon , Siskiyou Klamath River , Siskiyou Martins Ferry 61-62, 65-74 , Klamath " " 74-91 , Humboldt Orleans 57-74 , Klamath " 74-open , Humboldt Sawyers Bar 58-74 , Klamath " " 74-open , Siskiyou Trinidad 51 , Trinity " 51-74 , Klamath " 74-open , Humboldt Weitchpec 58-60 , Klamath " 91-open , Humboldt Yocumville 69-74 , Klamath " 74-91 , Siskiyou I would imagine that tracking down Klamath County records may be an interesting challenge. Has anyone done this? It would be interesting to have someone post their experience in chasing documents from ANY community/county that has had boundary changes. Have fun, Carolyn
