Thank you both for your help. I do appreciate that a 1935 marriage is going close to the possibility of at least one of the parties still being alive. Nevertheless, the info seems to indicate that they were both born more than 100 years ago.
Importantly for me, the two witnesses were unknown to me until now. They were the brothers of the bride and all three were my mother's first cousins. One named after his father, the other after his grandfather.
Thanks again,
PeterB
