Hi Patricia, The MANGUM surname somehow connects to my tri-racial WEELDON/BROWN family line, so it is doubtful that I shall ever find out just how. I am tho, curious abt your Dad's middle name of ROLAND as it is found often in the Native ancestry I have been able to find. Curious also abt your DOUGHTY surname as I wonder if it could possibly be connected to DAUGHERTY? Hope to hear from you. Sincerely, carol wheeldin warren.
