Leontin Porins Gangnuss Trusinskis

The following image is of an Australian immigration document from 1950. It is of my grandfather's sister, Leontine Trusinskis, who was married to someone with the surname Gangnuss, had a son named Helmut and then seemingly remarried to a gentleman with the last name of Porins. She and her son and husband were from Latvia. If you are related to this person contact me by posting a message here! I believed she died in Australia in March, 1991.
