Ambjørg Ivarsdaughter Einang, born in 1871

This girl was born in Vestre Slidre in Valdres, Oppland, December 31, 1871. Her parents were Ivar Andersen Einang and Barbro Eriksdaughter. This couple's baby was baptized March 24, 1872. She emigrated to the US April 18, 1902 - and she was named Ambjørg Einang, she was 26 years old and she was not married. She went rather rapidly to Sioux City in Iowa, where she for many years worked for Mr Call. She was - in the 1920-census - registered as an unmarried servant With the Call-Family in this city in the mentioned state. Could you please find the address for me and the name of the American family living there, please! Is it possible to find out how long she stayed there? When she retired, she came to Norway - the place where she was born, and she died and was buried there. Best regards, Anne Benum
