ooops sorry, pressed wrong key. Marc tells us:
Although many think that Queen Natalia was poor,she died very wealthy because she inherited all Obrenovic fortune after death oh her son King Alexander(plus her Keshko-Strudza estates)...In her testaments she left all that to Belgrade University and to descedants of Jakov,Prince Milosh's brother who are still present in the male line and live in Serbia under the surname Jakovljevic!
was this a member of your family?
