Die Littauischen Wegeberichte mentioned Manewidendorf near Hieraniony (now in Belarus). Other patronymic territories included Vishnyeva, Zhuprany [be],[6] and possibly Braslaw.[7] He also had possessions in Vilnius. He funded the Chapel of St. Albert and St. George (his and his brother's Christian names) within Vilnius Cathedral,[8] which is possibly the present-day Chapel of Ignatius of Loyola, and was buried there.[9] He also funded a Catholic church in Braslaw.[3] His donation to a Franciscan monastery in Ashmyany in 1407 is the first known surviving personal document of a Lithuanian noble; the surviving copy is a forgery, but likely was based on a similar document.[10]
Manvydas was married twice: Jadvyga and Juliania. Jadviga's origin is unknown. Polish historians Władysław Semkowicz and Marceli Antoniewicz have attempted to identify her with Jadwiga of Leżenic [pl] who adopted Manvydas in the 1413 Union of Horodło.[12] Information on Juliana is conflicting. Origo regis Jagyelo et Witholdi ducum Lithuaniae mentions that Juliana, who later married Manvydas, was wife of Butrimas, the murdered nephew of Birutė and cousin of Vytautas. Jan Długosz mentions that Juliana was a widow of Narimantas, who died in defense of Vilnius in 1390, and a sister of Anna, wife of Vytautas.[12] Lithuanian historian Inga Baranauskienė suggested that Manvydas rose to prominence in the service of Vytautas due to them being in-laws and that Jadviga (mentioned once in a 1407 document) was just a baptismal name of Juliana.[14]
