This may be the sister but she used Olsson, not Andersdotter, when she emigrated. She was a dressmaker, seamstress (sömmerska).

The Söder CD says that she entered 7 November 1897 from Kalmar in Uppsala län and went out to America 11 June 1898. Her address was Hornsgatan 104,106; Bränkyrkan 93,95 (kv. Ufven Mindre 1). (I can't explain that address so hopefully the Swedes can.) Perhaps there was a misunderstanding about which Kalmar she came in from.

This person, with a different set of given names (an error?), was born 7 June 1872. Emibas isn't complete, however.

I see that the father was Anders Olsson and the children (or at least a couple of children) apparently used his patronymic instead of keeping up the old patronymic traditions. This was a time of transition and the old customs died sooner in cities, so I'm not surprised they didn't use Andersdotter.
