Thank you. In 1905-06 Agostino Penna and his family settled in Sonoma County in the hills above Guerneville, near the Cinnabar mine. After the Earthquake, which destroyed part of the mine, Agostino moved his family to the west side of Santa Rosa where building was occurring. In the 1910 Census, Giovanni Penna is shown living in "Redwood Township" which fits the area where the old Cinnabar mine was. I believe Giovanni to be the brother of Agostino, (he had a brother by that name who went back to Italy.) Now I can estimate the year of Giovanni's birth. Does anyone have any more history of the Cinnabar mine? There is a snippet in the slim volume "Images of America -- The Russian River", by Simone Wilson, Arcadia Press, 2001.
