Rimgailė
Rimgailė was daughter of Birutė and Kęstutis, Grand Duke of Lithuania, and thus sister of Vytautas the Great. Rimgailė or Rimgailas is a typical dual-stemmed pagan Lithuanian name constructed from rim- + gail-, which is quite common in Lithuania at present.
By marriage with Henry of Masovia, she was Princess of Masovia for about one year, until the death of her husband. Jan Długosz in his chronicles wrote that to marry her Henry resigned from the title of Bishop of Płock. She was among the suspects in the death of Henry.
Her second marriage was with Alexander the Good, Voivode of Moldavia. Upon the politically motivated divorce she was given the customs of the town of Siret and 40 villages. Also, as part of the divorce settlement Alexander the Good promised to pay her lifetime income worth 600 Hungarian gold ducats or florins payable in two installments.
