I am a direct descendant of Ferdinand Zielsky and Louisa Luebka. Their son Frederick August Zielsky (b 20 May, 1864...d 16 Dec 1951) was my father's grandfather. Please look at my Gibbs Family tree on acenstry.com as it should illustrate this fact.
My grandmother's maiden name was June Fern Zielsky and married a Gibbs.
I would love to trade any information. I even have old original letters from F.A. Zielsky that my dad kept and passed on to us, his sons.
