She was was born 19 February 1886, the daughter of farmer Johan Peter Nilsson and Anna Kristina Magnusdotter Åkerslund, Ramkvilla, Småland, Sweden. She had four younger brothers Albin, Emil, Frans & Edvin, a younger sister Ida and two elder sisters Alfrida & Hanna.
Albin Emil & Edvin had previously emigrated, changed their name to Lander and were working in the Chicago era. Helmina travelled together with Elin Braf, also from Ramkvilla. They boarded the Titanic at Southampton as third class passengers. Helmina was destined for Joliet, Illinois.
When accident occurred, the girls dressed themselves and Helmina rushed away in advance while Elin was left behind to pick together a few things. Helmina reached (probably) Lifeboat 13 and was saved. Elin was lost.
In New York, she was given an unknown sum of cash and a ticket to Joliet.
In 1918 she married Albin Linder and they had two sons. After some years they returned to Sweden and lived at Hillefällan, Rörvik, where they conceived a daughter. Helmina died in the spring of 1971.
