My mother immigrated from Romania 55 years ago. Now she wants to travel back for sight-seeing, but all the names have been changed. The name of the street she grew up on was Filimon Sirbu. How can we locate its current name? Bacau municipal services were not very responsive.
According to this PDF document from the official site of the hall of Bacau the new name of the Filimon Sirbu street is GEORGE BACOVIA.
I do not speak Romanian, but google translate says that "Denumire veche" means "old name". Also, it seems that this street had a few other old names beside Filimon Sirbu: "Gimnaziu", "Regina Maria" and "Calea Moinesti".
Here is the street in Google Maps, perhaps an aerial view helps your mom in recognizing it.
