Here are the areas we'll browse.
The first region on the agenda is Hesperia, the area where Ethelbert & Jane settled. Their neighbors in Bryson, Ezekiel Ray, became their family when Jeff Harris married Callie Ray. Jeff & Callie lived some of their years near Bradley and had three sons, including Wayne's father Martin Ray Harris, who worked his ranch in the Copperhead Canyon area. As Wayne grew, his horizons expanded into the Lockwood Valley (and beyond, of course, but the rest of that history is on a different map, one not yet made :-).

The Hesperia homesteads are roughly halfway between San Francisco and Los Angeles.
