Louisa (Frothingham) Molson (1827-1910)

After her mother's death in 1843, she vowed to stay with her father at Piedmont as his companion and housekeeper for as long as he may live. Her eventual husband, John H.R. Molson, had to wait thirty years before he could marry her, by which time she was too old to have children. They continued to live at Piedmont and she worked closely with the Montreal Protestant Orphan Asylum and helped pioneer the cause for higher education for women. Among many other charitable bequests, she gave over $120,000 to the Protestant Hospital for the Insane; $240,000 to the Montreal General Hospital and $100,000 to the Royal Institution for the Advancement of Learning.
