Hi my name is Ladessa Thompkins. My 3rd ggrandmother was Rowena Lucretia Monroe. I have been trying to find out who her mother and father is but have found it rather difficult. Her husband was John Henry Plank. She had a daughter who was Elanor Lucretia Plank who married William Henry Carrington. In my research it has said that she is related to the President James Monroe but I have not been able to figure out how. If you could help me please respond back.
