My research has led me to believe "James Miller", the 13th child of Cornelius Hendricus Miller, is James K Harrison MILLER. James was born 1 Mar 1805 in Oswego Co, NY. and died 21 Feb 1885, Dallas, Taylor Co, Iowa. He moved his family to Taylor County, Iowa before 1870. The wife of Cornelius Hendricus Miller was Mary Maria "Polly" Muller, born 1761, Claverack, Columbia, New York. Her father was Cornelius Christofel Muller and mother was Margarita Ketelhuyn (not confirmed on mother).
John Lee Parons, b. 1822 in NY and died 1920 Taylor Co, IA. His first wife, Mary E. Fuller, was dtr of Lewis Fuller and Catherine "Kate" Miller (dtr of Cornelius Hendricus Miller). After she gave birth to about 4 children in NY, she died in NY. John Lee Parsons then married Lydia Caroline "Libby" MILLER, dtr of James K Harrison MILLER, above, and his wife Laura "Laury" PIERCE.
I hope this helps. Nancy McDonald
