Possible match: On Ellis Island there is Anna Petterson (age 25) arriving to New York Feb 27, 1893
Last Place of Residence: Gothemburg. Arriving on the ship S/S ETRURIA.
This Anna lists her destination as Michigan which could be a town/city or the state.
There is a Michigan City Indiana which is not far from Chicago - where her sister could have been.
1) But where did she go then? To her sister Maria?
2) She is back in Sweden Dec 29 1906...for some reason...what ship did she use back?
S/S ETRURIA left Liverpool Feb 18 and arrived to New York Feb 26 1893...was this the ship she used?
People arriving was often written down a day after reaching New York (see Feb 27 above).
