Query on Christina Dorothy PARKER husbands

Christina Dorothy Troy 1900-1986 daughter of John Parker and Mary Jane "Jennie" Parker is on Geni with 2 husbands

1. 1918 Private
2. 1927 Alban Stanislaus Troy

I think this is 2 Christina PARKER's confused

NSW Marriage Records list

• 1470/1918 Arthur J BATES married Christine PARKER at Crookwell
• 5314/1927 Albert S TROY married Christina D PARKER at Sydney

If these were the same woman - the 1927 married would be as Christina D BATES rather than PARKER.
