Daughter of John and Elizabeth Mauck Pittman, granddaughter of Nicholas and Catherine Snapp Pittman of Virginia. Catharine emigrated to Harrison County with her family ca. 1808. After the deaths of her parents, she apparently lived with her younger brother David Pittman (1850 Census) until her death.
The family name is spelled Pitman or Pittman, depending on the branch of the family or the particular person writing the name on documents.
