The information you have on Harriet Gertrude Northrup sounds correct. Charles Walter Manahan was my Grandfather's (Ivan Judson Manahan) brother. Both children of Charles Henry Manahan and Emma Ellen Lee. In my records I have that Charles and Harriet had four children, but I do not know there names or dates of birth. If you have any information on the children I would appreciate it if you could email me at [email protected] I will be willing to share what information I have with you. Thanks, Gerald
