Can anyone say what might have motivated a gold-country (Placer Co) miner to relocate to SLO city in 1869? Was the RR going through then? My ancestor's first child was born in SLO in that year. Within two years, he and fam had moved to Sonoma Co. (His name was Marshall FLORENCE.) Thx anyone. Alice Mitchell Monroe, WA Researching Goodnow/Lukens/Cox/Wall/Florence/Bird/Melino
