Hello Ed,
My name is Federico Lahm, I'm from Argentina, and I am trying to gather infomation about my great-grandparent's birth.
My great-grandfather's name was Heinrich Lahm, he was born in 01.10.1905 on Crvenka. His father was called Heinrich as well, and his father was called Friedrich Lahm. In a document called "Tscherwenkaer Familien" I found via Internet, I saw a comment in German that said something like "Friedrich Lahm had got close acquaintances with the Lahm families, who came from Györköny".
Do you have any documents that follow up the families that were born in that town? Tell me if you need any more information from me and I would gladly provide it to you, if I can.
Thanks in advance for your time and I look forward to hearing from you.
Best regards.
Federico Lahm
