Sorry, I have no idea if this lineage is of someone who was adopted by another family. This is only a genealogy book that lists surnames, dates, ancestry, etc. The KRON families listed start with a Johann Chritian KRON who was born 11 Dec 1798 in Fechingen, GER. He was son of Johann Ludwig KRON and Catherina Elisabeth FRANTZ. Johann (jr.) married Maria Catherina MULLER on 23 Jan 1823 in Bischmisheim. She married (2) Johann Jacob KAPPEL. Johann KRON had 11 children - 5 died while infants or toddlers, 2 went to America, and others married and stayed in Germany.
