Seeking info on a William L. GREEN, born ABOUT 1870 and Green family.

Marriage record: William L. Green to Doney Lee (b. 1872) McDuffey on 12/9/1888 in Yell Co., AR.

William and Doney Lee (aka Dona and Ledona?) had two sons: John and Columbus (aka Lum??)

Buried in Sunlight cemetery in Yell Co.: Ledona Green b. 1872 and died 1893. On tombstone it reads: To Our Mother, by John and Lum Green.

Would love ANY info on this Green family. Sons John and Columbus may have lived with their Grandmother GREEN after their mothers death in Green Forest, Carrol Co., AR.
I do not know what became of William Green or the sons.

ANY help appreciated.
