My Great Grandmother was Harriet Snover Louder. She was the daughter of James Cooke Snover and his 2nd wife Martha McCannel. It is information about Martha which I am searching. From census records I find her born in NJ in about 1830. All of their children were born in Pennsylvania. Does anyone have information about a McCannel family in either New Jersey or Pennsylvanian about that time? Any help would be greatly appreciated.
