Dear Carol, J.-B. Kléber had never marriage and no legitim children. He had two brothers. One of them was an "Abt" and i´m thinking he had not marriaged. The other one was emigrated to Saarbrücken (Saarland)and he had any children. One daughter of him had an daughter, who marriaged an "Jerchel". J.-B.Kléber is a son from Jean-Nicolas Kléber and his wife Regina Borgart. In an old german book about history, was written, that J.-N.Kléber came from Westprussia ( today Poland ). I know from my family, that there come from Westprussia. And our name is Kléber. My gr.- grandfather was Friedrich Kleber and his wife Maria Bischof.
