I have a photo posted below of A Teodor Ardelean.
I don't know exactly how they fit into my family, except they wrote a few times a year to my Grandma and Great Grandmother.
The last remaining address was Ardelean Todor 1636 Nadlac
Rai Banat, Jud Timison I believe (50 year old hand writing and ink)
I'm hoping that this is someone's relative as I have about 20+ letters I'd love to scan and share and learn more about.
