Lafve Mellblom and Kjersti Lindquist also known as Cecilia who went to Chicago before 1882

[Kim Melchior]

I just received a letter from a friend of mine. He asked if I could help him find his Swedish ancestors. This is all the information he has:  
 
My Great-great grandfather's name was Lafve Mellblom, born February 14, 1837 in Malmo or Stockholm, Sweden. I am told that he married Kjersti Linquist in about 1868 in Oslo, (Norway or Sweden?) (maybe Stockholm?). Kjersti Linquist was born on 1 May 1847 in Stockholm, Sweden.  
 
Around 1878-1882, both Lafve and Kjersti and all their children moved to the United States of America. (I would be interested in a passenger list on them if it is possible to find.) It is possible that Kjersti may have changed her name to Cecelia sometime after moving to the USA. They had about 4 or 5 children born to them before they moved to the USA. After moving to the USA, they had several other children.  
 
The first child born to the family died at birth or soon after. He/she was born about 1870 (maybe in Stockholm), Sweden.  
 
The second child is named William Merle Mellblom, born on 26 May 1871 (possibly in Stockholm) in Sweden. William Merle Mellblom is my great grandfather.  
 
The next child born to the family is Annie Charlotte Mellblom who was born on 3 March 1873 in Malmo or Stockholm, Sweden.  
 
The fourth child born to the family was Hilda Caroline Mellblom who was born on 4 May 1874 or 1878 in Halsingborg, Sweden.  
 
The fifth child born to the family was Charles Mellblom who was born in September 1878 - 1880 (or 26 May 1879) possibly in Stockholm or Halsingborg, Sweden.  
 
The sixth child born to the family was Ida Theresa Mellblom who was born on 12 July 1882 in Chicago, Illinois in the USA.  
 
The seventh, eighth, and ninth children born to the family are Edwin Ferdinand Mellblom, Adolph Alfred Mellblom, and Victor Harold Mellblom - all three are born in Chicago, Illinois in the USA, respectively on 7 February 1885, 2 May 1887, and 10 February 1891 - although I doubt that the information about these last 3 children could be of any use to you.  
 
Kjersti may have used the name Cecelia even while in Sweden. I am also told that Lafve may have been a gardener in Oslo, Norway. I have another report that Kjersti's maiden name may have been Granqvist, and that she may have been born in Kristiansand or Kristiansund, Norway on 1st or 2nd of May 1854. (I think the 1900 Census record of Chicago suggests the 1854 birth date, but I think the 1847 date is the correct one.) Needless to say I am uncertain about some of the information supplied above.  
 
Anybody having any suggestions?
