Wikipedia Article on "Daniel of Galicia" (1201-1264): 

In the last years of his reign, Daniel engaged in dynastic politics, marrying a son and a daughter to the offspring of Mindaugas of Grand Duchy of Lithuania and acquiring territorial concessions in Poland from the latter. Another daughter of his, Ustynia, was married to Prince Andrey Yaroslavich of Vladimir-Suzdal. He also arranged for the marriage of his son Roman to Gertrude, the Babenberg heiress, but was unsuccessful in his bid to have him placed on the ducal throne of Austria.
