You probably are looking for The CAGenWeb Project page for one of the following counties:

At some point in the near future, this page will redirect. Rather than automatically redirect you now, though,
we thought that we would give you the opportunity to see that this page has been moved
and to update your existing bookmark with the new link or to
notify the webmaster of the site from where you followed an old link.

The new link to The CAGenWeb Project page for the county you are seeking is:
Amador County www.cagenweb.com/amador/
Calaveras County www.cagenweb.com/calaveras/
Mendocino www.cagenweb.com/mendocino/
Sonoma www.cagenweb.com/sonoma/
Stanislaus www.cagenweb.com/stanislaus/

We apologize if this move has caused you any inconvenience.
