The link above seems to connect "Ida Kleber" the daughter of Henry Kleber (according to genealogy records - 1858-1946) with Ida Kleber the singer and composer mentioned in other accounts. Needed only one account that suggested that they were, indeed, the same person (and not, say, cousins with the same name- as does happen - after all, there were several Henry Klebers just in different generations of this family, though here the dates seem right!- or a coincidence.) (now +non-PD-EU, btw.)
