Mary must have been an older sister to Niles Frederick. Mary Valborg Norlin was born in Sweden April 9, 1853. I believe she did not immigrate to the US with her parents, but later sometime between 1880-1881. She had a daughter Nellie (married Raub)born May 31, 1879 in Sweden and her next daughter Minnie (my great grandmother) was born December 1882 in Kansas. I have photos of both Nellie and Minnie together.
Gustav lived with Mary and her husband George Moody until Gustav passed away in July 1911. The 1900 census indicates they lived in Topeka, KS. The 1910 census indicates they lived in Salina. My grandmother Jewel was born in 1922 - and her grandmother Mary lived across the street from her in North Topeka.
