Hi Bud:
I did visit the El Dorado County Museum research room last week before we left town. In spite of the kind help of the volunteers there, no postive mention could be found of Arthur/Otto Peterson or his wife Cruzita. There were some records for an Arthur Petersen on the county clerk's website:
http://www.co.el-dorado.ca.us/countyclerk/index.htmlFollow the link and search "recorder's index by name" to view the records. When we are back in town, I will be glad to look at NewspaperArchive, also. The Mountain Democrat has been around a long time, but archive searches now require a fee.
One thing that made searching difficult was not know which area between the county line and Placervile that the beer parlor was located----east, west, the town of Lotus or Latrobe in the other direction? Do you have any more info that would give that detail?
I also wondered if the state liquor licensing agency keep records back that far.
Shanna
