Joyce, I did some research in my files and found your Great grandfathers cousin Nancy Marinda Bradley. Here is how we are connected.
My James Youngblood and wife Mary Polly BRADLEY are the great grandparents to James Monroe Youngblood who married Nancy Marinda T. B. He was her second husband. It seems they have both been married a few times. I beleive James was married to an Elizabeth Sharp in 1846. Then may have married after Nancy's passing to a Cooper. He had with Nancy at least one child that I am aware of.: W.G. Youngblood, born 1873 AK. who married Camile E. (lizzy)Sipe. You can find this info and ancestry.com and familysearch.org. As for the BRADLEY connection, Nancy's father is Asa Bradley from NC, my Mary Polly Bradley is from Johnston NC. Familys often intermarried from generations to generation. I wouldnt be supprized if Mary is an aunt or distant cousin to Nancy.
Your James Youngblood and my D.F. Youngblood (who married Ruth Ann Reeves) were first cousins.
I have a complete file on the Youngblood family and many of the wives as well. This is on my mothers fathers side. Connecting to my Youngbloods I have the surname HOUSE. Marquerite House daughter of Adam house born 1754 Jefferson MO. Married Anne Wheat.
Well I hope I didnt over load you. email me if you want further info.
