Who was Daniel Artis‘ wife? Or, in any case, the mother(s) of his children Clara Artis Edwards, Henry Artis, Loderick Artis, Prior Ann Artis Sauls Thompson and Mariah Artis Swinson?

That Daniel appears in the 1850 and 1860 censuses without family suggests that he was married to an enslaved woman who lived apart from him with their children, but identifying evidence is scanty:

• I have found no records for Clara Artis Edwards that indicate her mother’s name.
• When Henry Artis married Lena Edmundson in Greene County in 1903, he listed his parents as Daniel Artis and Eliza Artis. Henry Edwards (Clara Artis’ husband) and Marcellus Artis (Lodrick Artis’ son) were witnesses. Though his age is off by about ten years, this appears to be the right Henry. Daniel Artis registered his two-year marriage to Eliza Faircloth in 1866. Was Eliza really Henry’s mother? Or his step-mother?
• Ditto for Loderick Artis, except: in Baalam Speight’s pension file, there is an affidavit from Lewis Harper. Harper asserted that he was Loderick Artis’ brother.
• Nothing for Prior Ann.
• When Mariah Artis married Jesse Swinson in Greene County in 1879, she listed Ruthy Edmundson as her mother and noted that she was living. (Is this the Ruth Edmundson, age 59, wife of Samuel Edmundson, listed in the 1880 census of Bull Head, Greene County?) Mariah’s death certificate lists her mother as unknown.
• In the 1880 census of Bull Head, Greene County, Mariah Sauls, age 60, is listed as either Mariah Sauls Edwards or her husband Timothy Edwards’ grandmother. As Mariah Edwards was Prior Ann’s daughter, was Mariah Sauls Prior Ann’s mother?
