Notes:

From Sandra, Sept 2025:

Shirley was one of the bridal attendants for the wedding between John F. Kennedy marriage to Jackie..

Contemporary reports of Jackie's wedding party list "Shirley Oakes" among Jacqueline Bouvier's bridal attendants / bridesmaids. I found multiple period/newspaper-derived references that include Shirley Oakes in the wedding party.
Virginia Chronicle

Multiple family/genealogy pages connect Shirley (Oakes) Butler to the Oakes family of Nassau and report she was in a serious car accident in 1981 and is recorded as dying in the mid-1980s (some pages list 1986)
