Federal Census extractions

This is the 1850 Federal Census for Washington County (Now mostly Columbia County) Oregon Territory. In 1850 it included population in what are now Columbia (mostly), Washington (many), Multnomah (few), and Clackamas (few). Some of the area now in Columbia County was then in Eastern Clatsop County.  The census is here presented in sections, to speed downloading.

Unfortunately, for 1870 they did not index by county so you have to search the entire state.  You really need to filter by unique first and last name to narrow it down.
