Maps of Sonoma County By Town (or Township)

First line will have: MAP NAME: YEAR, ORIGIN COLLECTION.

Second line has information about the map, mostly what TOWNS / TOWNSHIPS / LOCATION NAMES the map shows.

** I want to make these maps (and other documents) searchable by name, so I will have to transcribe the names found on the maps. I think I will have to put the lists of names on a different page, but I'll  work on that. But YOU can help me with this project! Simply go to a map below, carefully type up all the People Names that you can find, and email the list to me with the name of the map through the Queries page. I will gladly give you credit for the submission! And you will have helped others who are doing research!
