I am descended from Waacks in the area of Quincy,
Adams County, Illinois. The few I have traced
back to Germany came from close to Wismar (Beidendorf
and Zickhusen) The names Dora and Dorothy have shown
up in my searches. I do not have a lot of info, but
either send me more info to compare or enter Waack
into my search engine(s) at
