Maria of Bosnia
Maria of Bosnia (Marija Kotromanić, born after 1333, died 27 April 1403) was a Kotromanić princess, likely a younger daughter of Ban Stephen II. In 1352 Emperor Charles IV arranged her marriage to Ulrich V, Count of Helfenstein, and she travelled to Passau for the wedding. A supporter of the emperor, she bore six sons and three daughters.
Widowed when Ulrich was killed in 1372, she spent her later years at Bühringen. She founded a hospital in Swabia and was probably buried at Überkingen.
