I grew up hearing stories about Mat and Justina. I'm fairly sure they lived in Jenny Lind, Arkansas as well as Clinton, Indiana, and may have finally settled in Oklahoma.
They were apparently cousins of my great grandmother Aloisa Rom, who emigrated from Tschermoschnitz, a tiny town in Gottschee. Aloisa married John Henigman, (originally Honigman)who also came from the same area. My grandpa was August Henigman, their son. There is a great deal of information online about the Gottschee area.
Hope this helps!
