I am looking for information about the parents of William Williams (1838-1917) of Meridian MS. According to census records (1900, 1910) he was born in North Carolina. According to my mother, aunt, and grandmother his "first last name was Lloyd or Loyd" and he was adopted by the Williams family, date unknown. He served in the Miller's 9th Cavalry (MS) in the Civil War. He is buried in Stinson Cemetery in Meridian.

His children are:
Irene (1876-1963) my great grandmother, her mother is unknown
Eliza J (1881-1961)
George (1886-1954?)
Blanche (1887-1982)
Lucile (1893-?)
Sadie G (1896-1980)
Flora V (1898-1973)
Katie Lee (1901-?)
Walter D (1905-1907)

Wives:
Matilda Davis (no birth or death dates) likely mother of Eliza, George, and Blanche; info from SSN application of Blanche Williams
Mary Magdalene "Maggy" Hardin (1864-1906) likely mother of Lucile, Sadie, Flora, Katie Lee, and Walter D; info from SSN app of Flora

Who is Irene's mother? Who are William's parents?
