My gGrandfather, Antal Tacz was born in Bustyahaza, Maramaros County, Hungary in 1846.He married Etelka Marzso (b 1857) and had eight children (Maria, b. 1880; Lajos, b. 1882; Anna, b. 1883; Julianna, b. 1884; Sandor, b. 1885, d. 1885; Laszlo, b. 1888; Ilona, b. 1890 and Kalman, b. 1893, d. 1931).Antal worked for teh Royal Hungarian Railways in the Deprecen area of Hungary.He retired in 1907 in Szatmar-Nemeti (Satu Mare).At some point the spelling of our surname was changed to Tatz from Tacz.We have evidence that Ilona (Ilonco) was living in Kolozsvar (Cluj-Napoca) in 1964.I need help finding the name in Romania.I also need help regarding how to go about researching in Romania.I also need help sorting out name changes and reasons for them. (Boy, do I need help!) Our name went from Tacz to Tatz in one generation and I have indications that Tacsi is a variant but I cannot confirm this.
