In case you get this response, I see it has been three years sence posted. I am interested in your Jisa family. I have been working on the Jisa's in Illinois for a few years now and have been in touch with some family members.
Was just wondering if a Joseph Jisa or Katherine Jisa Drnec could be related. Joseph was born in about 1840 and
Katherine in 1846. Kewaunee County is not fimilar but I thought it could be a try.
