Marriage and children[edit]

Leszek married Grzymislawa of Luck in 1207. She was the daughter of Grand Prince Ingvar of Kiev, the ruler of Lutsk and its vicinity, a part of Galicia. Thus this marriage was part of Leszek's policy of eastward expansion. Leszek's and Grzymislawa's daughter Salomea was born in 1211. She married King Coloman of Galicia-Lodomeria,[6] the son of King Andrew II of Hungary. The marriage occurred in about 1215 when Salome was 4 and Kaloman was 7. They were the intended rulers of Galicia–Volhynia, but as noted above these plans failed and they never took up rule in that area.

Leszek and Grzymislawa were also the parents of Bolesław V the Chaste, who assumed the Polish throne at Kraków in 1243, and Helen, who married Vasylko Romanovich of Halych, son of Roman the Great.[7]

b) HELENA (-1265). Her origin is confirmed by the Russian source cited by Baumgarten which specifies that Prince Bolesław V was the maternal uncle of the children of Prince Vasilko[398]. Baumgarten records the death in 1265 of Helena, wife of Vasilko, citing a Russian source[399]. m (1248) as his second wife, VASILKO Romanovich of Galicia Prince of Bielsk, Luck and Vladimir in Volynia, son of ROMAN Mstislavich Prince of Galich, Grand Prince of Kiev & his second wife --- [of Byzantium] (1203-1269). He succeeded his brother in 1260 as VASILKO King of Galich.
