Sven Magnus Johansson to USA June 1869

[Sue Beckius]

Sven Magnus Johansson born March 08, 1834 in Hult parish, Jönköpings. Emig. thru port of Göteborg for New York the first week of June 1869 with wife. Unknown if their children were born in Sweden or America. Making the trip at the same time were two of Sven's sisters:
1.)Emma Johansdotter born after 1834 and single.
2.)Anna Elisabet Johansdotter born Feb. 21, 1831 in Hult. With Anna were her husband Anders Petter Andersson and four young children: Anna, Johan August, Ida and Emma.  
I am seeking information on the name of Sven's wife (and children, if any)or other information to help in locating him on 1870 Chicago, Illinois census records. Would also appreciate full name of younger sister Emma and her birth information.
Thanks for any help,
Sue
