My ancestry has an Anna Barbara BEUTLER born in Walddorf at the right timeframe to be married to your Daniel WALZ. I do not know who she married but wouldn't be at all surprised if it is a WALZ. I have several WALZ and BEUTLER ancestors from Walddorf and Monhardt, Wuerttemberg. Can you give me any more details? Feel free to email me privately or on list.
