Sarah Larkin born Cecilia Larsdatter

I have brought this subject over from the general Norwegian genealogy. I am trying to find out what happened to my great aunt who had the married name of Sarah Larkin living in Chicago Illinois sometime around 1900.This is her birth record ‘ToreL’ found her emigration under the name ‘Cesilia Larsdatter Grane’ (Graue) which helped establish a pre 1880 possibility for a USA census clue but I can not find any information about a Sarah Larkin living in Chicago in 1900. This is where she was mentioned in her brother John J Larson’s biography John J. Larson, a prominent and successful business citizen of Whatcom, owning and operating the finest livery line in this city, was born in Voss, Norway, January 27, 1864. He is the son of Lars and Ingeborg (Maringa) Larson, the former of whom was born in 1817 and is a resident of Graue, Norway, where he was engaged in farming and logging. The mother is also a native and resident of Norway. Our subject has three brothers and two half-brothers, two half-sisters and two sisters: Anders, aged fifty-four years; Lars, aged fifty-two years; Neils, aged forty-three years; William B., of Whatcom; Mrs. Anna Helgeson, of Britt, Iowa; Bertha, of Wisconsin; Mrs. Sarah Larkin, of Chicago; and Mrs. Belle Olson, of Seattle. I have become pretty self-reliant on my research, but I have come to a 11 year dead end on her and what happened to her.
