The 1920 census image clearly shows the husband's name as Carl instead of Kyle, and his birth year is earlier than the information you gave, so there seems to be a discrepancy there. It looks like Henry was not Molly's son but Carl's/Kyles's from a previous marriage?? The birthplace of Henry's mother is KY instead of MS.
