Christine Elisabeth cannot be a daughter of Johann Gottlieb Grosschopff and Anna Beata Östedt for two reasons:
1) in Russian she was called Vasilievna, not Iwanowna
2) there is a record in the birth register in which the parents of Christine Elisabeth are Wilhelm Bernhard Groschof and Elisabeth geb. Balm (Palm) ( ЦГИА ф.708 оп.1 д.55 л.71).
