Richard Mansell who married Elender, and it was his son William who is linked to Morning Dove. Just to make it more confusing, Richard Rice Mansell and Elizabeth Mobley also had a son named William Lovit.
was a settler in western Tennessee. Mansell is a French name--its literal translation is the man from Le Mans. The Mansells migrated from Norman France to Scotland, and then later to Ireland. In the 18th century the family came to the American Colonies. William Mansell fought with Andrew Jackson in the Indian Wars of the early nineteenth century. He fought with Old Hickory in Alabama, at the Battle of Horseshoe Bend, and later in Florida too.
Returning to Tennessee from the Indian Wars, William Mansell married Elvis' great-great-great-grandmother. Morning White Dove (1800-1835), in 1818. Morning White Dove was a full-blooded Cherokee Indian. The appellation 'white' in Morning Dove's name refers to her status as a friendly Indian. Early American settlers called peaceable Indians 'white', while 'red' was the designation for warring Indians or those who sided with the British in the Revolutionary War. It was common for male settlers in the West to marry 'white' Indians as there was a scarcity of females on the American frontier. Elaine Dundy says of the marriage, William Mansell gained 'age-old Indian knowledge of the American terrain; of forests and parries; of crops and game; of protection against the climate; of medicine lore, healing plants as well as something in which the Indians were expert--the setting of broken bones'. Moreover, added to Elvis' lineage were Morning White Dove's ruddy Indian complexion and fine line of cheek.
Like many other settlers, the newlyweds migrated to Alabama from Tennessee to claim lands garnered in the Indian Wars. The Mansells settled in Marion County in northeast Alabama near the Mississippi border. Morning White Dove and William Mansell prospered in Alabama. Their land was fertile and they built a substantial house near the town of Hamilton. They had three offspring, the eldest of who was John Mansell, born in 1828, and Elvis' great-great grandfather.
