It is possible that you are descendant of Croat who in the Turkish time converted to Orthodox Christianity and later became a Serb.
I give example of a person from Dalmatia, which by Serbian myth came from Kosovo or East Herzegovina to Dalmatia but genetics of that person does not come from there.

It is logical that part of local Croats in the Turkish period converted to Orthodox Christianity and Islam, and it now evident in genetics.
After year 1804..
When you examine origin of šumadian population, we see that among them there are very few natives. In Šumadian areas: Kačeri, Gruži, Lepenica, Kragujevac, Jasenica, Smederevo, Danube region and Jasenica, Kosmaj and in villages near Belgrade we are investigated origin of 8894 genus with 52,475 houses. Of this number, only 464 genus with 3603 houses are natives, there are and population of unknown origin (470 genus with 2464 houses), but all other Šumadian (central Serbia) population was migrant and immigrant families and they have 7960 genus with 46,408 houses. Sumadia settled immigrants from almost all parts of our present-day kingdom, but most of the local Dinaric areas, that is Montenegro, Bosnia and Herzegovina, of Sjenica and Novi Pazar, Kolasin, from Pešteri and Bihor, from Dalmatia (Croatia), Lika(Croatia) and other parts of Dinaric.
