Absolutely none of your names listed were familiar to me. However, I have Jaeck ancestors who settled in Wisconsin in 1879 from Friedeberg, Kreis Kriedeberg, Brandenburg i.N. Prussia. They first came to Waukesha Co. and then moved to Rock Co., then Jefferson Co. and finally Walworth Co. I have not been able to find any other family members other than my G. Grandparents (who were the emigrants) and their children and direct descendents. What part of Wisconsin did your Jaeck family members live in? Do you know where they emigrated from?
I have found other people with the surname Jaeck but can't find a link to my Jaeck ancestors (who began spelling their name Yake soon after they arrived. I'd like to hear from you. Good luck.
