William & Isa Ardrey - 1885
Close inspection reveals that the certificate is preprinted "In the Year of Our Lord One Thousand Nine Hundred and ___________" but with "1885" written in the blank. Seems unlikely they were preprinting certificates for 20th century marriages clear back in 1885. This certificate was probably filled out at least 15 years after the fact. It apparently is merely an "heirloom memorial" certificate, likely filled in by a family member years later.
