My MENDEL grandmother and many others in my family were born and/or died in Buhusi, Romania Vital records still exist however, you need to hire a Romanian researcher in order to access the files. My grandmother Fanny (Freida Sura Mendel) was born there is 1881. Following is the translation from Romanian of my grandmother's birth record. It clearly matches your reference for "Bohuss" (actually Buhusi.) . You should be able to obtain a copy of your great-aunt's birth record and other vital records for those in your family who lived there in the 1800's.
