I am afraid that just "speaking German" is not a lot of use. I am bi-lingual but I am not conversant with the old script - very few people are nowadays. I can make out quite a bit but would not presume to say it was all correct. I honestly think it is unlikely that the Amish people could help either, their language is too far removed from 19th century German, although it might be worth trying if all else fails. My advice is try the translators' site. There are defintely some people there who have helped in the past. Good luck with it.
