Notes

Margarete was baptised at the age of 41 years in Bourke, Victoria, Australia. The baptismal record names her parents and places them in Breslau; it shows her surname as "(Wendriner)", consistent with her being divorced from Ludwig Wendriner by this time. She is noted as being "now Madame Belmont" and the report of her death ascribes the same title to her.
