Meet two families who played instrumental roles in creating the railroads that became the West Coast destination for the transcontinental railroad. The Gibbons family arrived in Pennsylvania in the 17th century. The patriarch sat on the jury for that state’s only witch trail. The Cohens thrived in Jamaica as coffee barons, until Great Britain abolished slavery, that is. Dennis Evanosky will trace these families to California and discuss the important roles they played in early San Francisco, Oakland and Alameda history. He will also discuss the Edgar Cohen photographs donated to the Oakland Heritage Alliance. Edgar was an accomplished photographer who lived in Alameda.
