Not so far  -  all the relatives have now passed on that is why  I am researching that side of the family.
Lisalotte klug. -  born 1922 (approx). 1st married to (Jurgen ??) Hesse - son Jorg born 1944.
                                                        She died in 1990 s
                                                       2 nd marriage to Werner Czinczoll - lived in Bremerhaven        
Father Hans Klug married to Kathe. -  2 nd wife - lived in Bremerhaven.
Brother Peter married to Helga - lived in Hannover
Brother Manfred married to Erna - lived in Bremerhaven
All now deceased.
father- Hans Klug - could that be Johannis Klug ??
a marriage of Elisabetha Klug in 1893 in Homburg,Bayern,Germany gives her parents as 
Name   Johannis Klug
Gender   Male
Wife   Kath. Leis
Event Date   12 Nov 1893
Event Place   Homburg (Ba. Homburg), Bayern, Germany
so could your 2nd marriage  of Hans Klug to Kathe be Kath Leis ??
the only marriage I could find that might be a possible
