The information I have on Reuben Miller is that his father was Jonathan Miller and his mother was Mary Davis.
Here is what I have:
Jonathan MILLER was born 1710, and died 1779 in Bertie County NC. He married Susannah COBB, daughter of Edward COBB.
Jonathan MILLER (Jonathan MILLER1) was born 1744 in Bertie County NC, and died 25 December 1815 in Bertie County NC. He married Mary DAVIS.
Reuben MILLER (Jonathan MILLER2, Jonathan MILLER1) was born 1776 in Bertie County NC, and died 1822 in Bertie County NC. He married Sarah MIZELLE. She was born 3 December 1777, and died 1855.
