I have a substantial amount of Hirschfeld information from Hohenems, Austria. If you can let me know who your ancestors were I can focus on that branch of the Hirschfeld tree and send the information along to you. There is a Jewish Museum in Hohenems supported by descendants of the original Jewish families there (although many descendants are not now Jewish). The museum is hosting a descendants reunion at the end of July and I am going to attend. I'll be happy to e-mail you any information that I have. lloyd@lloydhanford.com
