The "Possible Sweden, Household Examination Books" is not so possible. That Signe Eleonora was born in Norrköping, Sweden, in 1892; I'm looking at them in Arkiv Digital: Kila AIIa:2 (1906-1910) Bild 3920 / sid 380 (AID: v164017.b3920.s380, NAD: SE/ULA/10523) - I don't think this family left Sweden.
Amanda was a popular name when the Swedish common folk started giving their children fancy names, and in the Swedish census for 1890 there are roundly 100 Signe Eleonora of various ages - just showing that the name combination was not unique. Although also not super common, either.
But you don't think your Signe Eleonora was born in Sweden, do you?
