Josefine Pedersen Ekeland Lambert

Can someone help me to find out what happend to my grandfathers sister? Her given name was Teoline Josefine, but I think she only used Josefine. She was born 17. july 1879 on Egeland, Vanse in Vest-Agder, Norway. In 1900 she was living in Vanse with her parents, and her daugther Jennie or Jenny. Jennie was born 23 feb. 1900 in Stavanger, Norway. Her father was Trygve Steenberg. In 1909 Josefine and her two children Jennie age 9 and Adver age 3 arrives in the USA. The imigrationpapers states that she had lived in the US from 1902-08. Her husbond name was Peder Lambert. I dont have any information about this family after 1909. Yvonne.
