The Kamariškės Manor site was mentioned in historical documents in 1583 as the Palivark of the Suviekas Manor, belonging to Martynas Komorovskis and his wife Beata Kmitaitė, whose family fortune Mr. acquired as dowry after the wedding. It is likely that he was the creator of the Kamariškės Manor, giving the estate its name (Polish: Komoryszki).
In June 1634, the last will of Jurgis Komorovskis (son of Martynas) was registered in the court of the Ukmergė Castle, drawn up shortly before his death, in the Kamariškės Manor.
The estates of Suviekas, Kumpuoliai, Pamūšys, and Radiškiai, owned by Jurgis, were divided among family members: his wife Marijona Sapieginaitė and sons – Jonas, Samuelis, and Elijas Komorovskis, later known as brave warriors in battles against the Muscovites and Swedes.
In the second half of the 17th century, Suviekas and Kamariškės were inherited by Kotryna, the daughter of Jonas Komorovskis (~1600-1661) and Konstancija Judicka, who in 1684 married the Lithuanian grandee Paulius Zaranka-Horbovskis. Thus, through marriage, Suviekas and Kamariškės passed into the ownership of the Zaranka family for over a century.
