Staff Payroll. Mary E. Walker got hired onto the staff of the new Capitol as a "toilet attendant," though in the 1900 Census she gave her occupation as "nurse." She was one of the earliest African American settlers in St. Paul. She was born in Virginia maybe in 1834 (Census records vary)and by 1857 she was married to Nace Walker and living in St. Paul. Nace died in 1883 and his obituary said he had moved to St. Paul in 1849. They had no children.
