I am new to Catholicism, so forgive me if I am off. Is there a family member who has her records? Parents or God Parents maybe? When I was an infant my mother had me Baptised Lutheran. Thankfully, when I started to convert to Catholicism I was able to dig in some old papers in a trunk my mother left me when she passed away and I found my Baptism certificate. Maybe your wife’s family also has her paperwork somewhere in a box or file. If not, is there any way to go in person to her parish and get the copies that way?
My husband was raised Catholic. I was previously married and divorced. We married 10 years ago in a civil ceremony. Once I have my Decree of Nullity for my previous marriage we plan on convalidation. I have about a year to wait as I just turned in all the required paperwork last week due to having to wait for some things to come in the mail.

I really need to get cracking on getting my husbands records from the parish of his youth. Thank you for reminding me that it’s not just my paperwork that needs to be in order!
I feel so much sympathy for you. It’s hard to wait to have your marriage recognized. My thoughts and prayers are with you.
