My grandparents were married in Regensburg, Germany. My grandfather was a part of the 250th Station Hospital and he married a German woman who was admitted to the US under PL 271 AKA "The War Brides Act".
Since my grandfather was living in or around a US military hospital, would their marriage have been performed under the aegis of the US military, or would it have just been a local area church that validated their November, 1947 marriage?
The hospital they stayed at, in modern times, has a church physically attached to it. Back then, they were definitely separate buildings.
I feel like it's reasonable to suspect that they were married in that church if it was indeed built at the time. However, who would take charge of the records of the marriage is my question in any case.
