I found a quite long interview with Andis Juska's parents in a bimonthly magazine. I am not going to translate it, I'll just post some scans with their home and other pictures and some facts I didn't know. So that article is about Daiga and Janis Juska - both tennis coaches, how they lived, met, played tennis, married etc.
They didn't have their own children, so they decided to adopt one from the orphanage. So Andis became a member of their family at age 2.5. He is their only son.
He didn't know he was adopted until quite recently, when he found an insulting comment directed at him on the internet which lead to conversation with his parents about his past.
Nevertheless, their relationship is as good as always.
