Hi,
I think that Johanna could have been daughter of Seligman Fürth and Elisabeth nee Ofner, but so far I have no evidence. This Seligman lived in Zichovice and moved to Cerkowitz. I have another daughter of Seligman and Elisabeth Sofie married to Josef Kaufried and a sister of Seligman Franziska Fürth married to Simon Kaufried. I think also that Karl Fürth married to Anna Kaufried might have been a brother of Sofie Kaufried nee Fürth. Most of this is on Geni, but I am still looking for the family of Selig and Elisabeth Fürth nee Ofner in the records at www.badatelna.cz
Best wishes
Thomas
