Since 2010, Isa is married to Mailo Gudhamun, the Ambassador of the Principality of Teressien to the Sultanate of Kyrenaia. The couple has three children, the twins Raik and Rainer (2011) and the daughter Elfi (2013).
In 2017, her husband was appointed Ambassador of the Principality of Teressien in Kyrenaia, the parents moving to Qalat al-Jabal, while their children were sent to their Uncle Nantwin. Said Uncle Nantwin sent both Raik and Rainer to a boarding school nearby. The family kept in touch via the Internet and the parents visited as often as possible, sometimes even combining both official business back home with a visit to their children.
Isa is a socialite, feeling most at home when she is among people, although she does like calm evenings with her husband as well.
Isa deeply loves both her children and her husband.
