Help with getting international adoption records

Hello! I was adopted from Guatemala when I was 8 months old, and I’m currently trying to learn more about my biological family and adoption records.

I have the initial adoption paperwork and have been able to locate some siblings who were born after me, but I believe there may be more relatives out there. I’ve also tried services like Adopted.com and AncestryDNA(i found my siblings there), but I’ve hit a bit of a dead end.

Does anyone know how to obtain additional information for an international adoption from Guatemala? Specifically, I’m wondering if there’s a way to contact the adoption agency involved, access adoption records, or find other resources that might help me continue my search.

Any advice or personal experiences would be greatly appreciated. Thank you! ❤️
