August Gustafson,SWE to Minnesota,USA,1860-1943

[Candy Weaver]

Hello, my husbands great grandfather was August Gustafson.  He was born in 28 April 1860, Backen,Hofva, Skaraborg,Sweden.  I believe his parents could have been Gustaf Jansson and Carolina(Magnusdtr). I have found a Gustaf Jansson from Fyrasen,Hova,Skaraborg,Sweden-christened 29 April 1825 his parents were Johs Andersson, mother Stina Larsdtr. I am looking for any brothers or sisters- or any relative connected to August.  We don't know of any of his family.  He immigrated to the USA in about 1889.
Any help would be appreciated,especially by his granddaughter, my mother-in-law, Arlene(Bloomgren)Weaver.  Thank you,  Candy Weaver in Canada
