When he attended school, his sister Sarah usually accompanied him. “Sally was a quick-minded young woman,” is the testimony of a school-mate. “She was more industrious than Abe, in my opinion. I can hear her good-humored laugh now. Like her brother, she could greet you kindly and put you at ease. She was really an intelligent woman.” ¹
