According to Registry of Births, City of St. Louis, Jessie Miller was born 3 June 1889 to William Miller and Maggie Kissel at Female Hospital, birth reported by W. B. Dorsett, M.D.
In all caps above her name, MAMIE is hand printed. There is no mention of changing her surname. In the margin: “By aff 7-20-1942”, “aff” probably meaning affidavit. She was known to her daughter as Mamie Jessie Oetzel.
Family lore says that William Miller died shortly after Jessie/Mamie’s birth. Mamie used the surname Oetzel after her mother married Fred Oetzel in 1894, and states Mamie Oetzel as her name at her marriage to William Stohlmann in 1910 (when the priest at St. Boniface’s rendered her name in Latin, it appears to be Marianne but is not really legible).
Where will I find the 1942 affidavit amending her birth record?
