Sansu I have found Lahr on my very detailed map I got from a very kind gentlemen in PA. I too have ancestors from Kreis Bitburg, town of Bauler, also very small. Your Lahr is West of Bitburg on Hwy/Rd 50, south just a little bit about 2/3 way to Luxembourg. It is actually not that far from Bauler. Hope this helps you out. Let me know if you need more information and I will do my best. Also of note, my map shows a church at Lahr. Happy Hunting Karen
