After emigration to the US Ahlberg served in the US Army, and lived in New York and Los Angeles, married and became an advertizing photographer.
In the early 1970s, Ahlberg became Holly, divorced, and was accepted at the Stanford University Gender Clinic. However she chose not to have the operation. In 1975 she informed her clients of her change, and lost only a few of them.
She retired in 1985 and has become an artist. In 2013, using Google Earth, she found a previously unknown archaeological site in the Atacama Desert, which has provisionally been named Nuevo Albergis.
