Thank you for your response. I have not found a Francis White Dunham yet. But I do know that John Wilmont Dunham had several siblings. Robert Dunham, Elizabeth Ann Dunham, Thomas Dunham ( I don't know the middle name on that one), William Henry Harrison Dunham, Jonathon Briggs Dunham, Walter Gage Dunham and Martha Wilson Dunham. John Wilmont Dunham's father was Elijah Dunham who married Anna Maria Briggs. Elijah's father was named Thomas Dunham too. He was born June 4, 1763 in Woodbridge Middlesex County, NJ died Sept. 15, 1850. Thomas Dunham married Elizabeth Traviss b. 5/15/1773 in Westchester county, NY d. 1820 I don't know if this will help you. I hope so. Do you recongize any of these names.
