Here is the emigration record from Oslo [Christiania] for Daniel & family:
Daniel Danielson f:    1826 Gräsmark  
         non-owner  left parish 25 Apr 1879
    wife Märta Jansdotter 24 Sep 1831
children Maria             1 Nov 1858
         Daniel            8 Nov 1862
         Stina             9 Dec 1864
         Anna Kajsa        1 Dec 1866
         Märta            24 Aug 1870
         Johan             1 Nov 1873
 
I am sorry butI did not record the ship's name nor the date of departure, although they would have been part of the record.   But, that may mean that the intended destination was also in record, and I did not write it down.  Keep your fingers crossed.  I will try to get to the LDS library next week and see if they have still have that film in the drawer.  
I am not sure if I told you but Daniel's father, Daniel Håkansson, was my grandfather's grandfather. His son, Nils, Daniel Danielsson's brother, and my gr-grandfather came to the U.S. and settled in Little Falls Wisconsin, just north of Star Prairie. We take our family name from Nils Danielson.
Regards, Stan

Jeff,  
The Swedish name Stina often became Christine in the U. S. And, Anna's and Christine's birth years are the same as those of Daniel's children.  Adding the other daughter, Martha, makes even a better fit, but gives no proof. Keep in mind that Daniel's daughter Christine should have come to the U.S. with the family, as she was only nine years old at that time, in 1873.  
The family may have taken the name Engstrom when entering this country.  There was one other family from a farmstead in the north of Gräsmark that took that name, but it was not a family related to Daniel, or at least seems not to be.  This family ended up in western Wisconsin in a township called Star Prairie.  It is less than an hour's drive from Minneapolis/St. Paul, and just north of New Richmond, Wisconsin.  
I find another Engstrom in Two Harbors, Minnesota.  That is up near Duluth.  He was Johan Magnusson in Gräsmark and born 1860 [I think really 1859] on Södra Ängen.  He took the name John Engstrom when he immigrated in 1886.  
I have found some Engstroms in other records from Gräsmark, but they do not seem to be related to Daniel.
I had a phone call about 15 years ago from a man who was an Engstrom.  I think he lived in Texas.  If I can find that info, I will send it to you.  I tried twice to talk with him again, but he never returned my phone calls.  
I am also looking for some emigration notes that I took some years ago.  This family probably left from Oslo rather than a Swedish port.  It is closest.  Oslo was still called by it's old name in those days, Christiania.    
I am somewhat fluent in Swedish, so let me write in the Gräsmark forum and ask if anyone knows about where Daniel and his family may have ended up.  
Hälsningar, Stan

Jeanette!

Hej!
I have a friend in Wisconsin who has about 40 letters written from Sweden between 1910 and about 1930.  They are from V. Torp, Lilla Alstad, Böste and a few other places.  Some were written by family members named Malmgren to their sister, Nanny, who was Mrs. Peter Fors in Wisconsin. Peter and Nanny had a daughter, Sadie, who apparently never married. When Sadie passed away the letters were left in their old Wisconsin farmhouse.
There are also the death notices of Magnus Malmgren, 1913, and his wife Kirsten Malmgren, 1932. Magnus was a skomakare.  
These are interesting letters that the family today should have. The children of Magnus and Kirsten appear to be Otto, Anna, Amanda, Edvard from V. Torp.  Peter Fors may have been from L. Alstad, and had a sister named Elna, married to a Karl Lundin.  Peter's father died 18 Nov 1919.
If anyone can help us to find the family and have them write to me on this site, we can perhaps get these letters to a proper home in Skåne. I shall forward all replies to my friend in Wisconsin.
Kan skriva på svenska om Ni vil.
