I am Kathryn Jean nee Wollangk Johnson
My father was Lawrence Paul Wollangk and his mother Eva Belle Engel. I'm at work but I believe her mother was a Mack but I will have to go home and check what the exact connection was.
My father was born in 1914 and since it would have been his grandmother, I'm not sure this connection would work. Let me check and I'll get back to you.
The Wollangk's are out of Fond du Lac and Oshkosh, WI if that helps. I believe there is only one family of Wollangk's and there are a few out there now.
Eva had at least one sister Una Engel.
At any rate let me check and I'll get back.
