I wonder if this is also my great grandfather, although my records show Norfolk, VA. Do you have records that show Charles Archer Simpson married Anna Augusta Henrietta Raetz? (She later divorced Charles and remarried). Charles and Anna were married in 1905, either in Virginia or Missouri. I do not know if Charles was married prior to or after his marriage to Anna.
Since your post, have you found any records going back further on Charles' parents and grandparents?
