JRI-Poland records her birth in Breslau in 1897. She is almost certainly the Betty Boldes listed in the Breslau synagogue community address list (ca 1930) at Tauentzienplatz 8, born 21/01/1897; among other residents is her widowed sister Else, as well as two other people named Boldes - Herta born 13/11/1892 and Herbert born 21/01/1900, who are likely to be her siblings or cousins.
