Help finding Olga Rott LB9N-Y5K, born in either Romania, Russia, Ukrania, or Kronau

AnneliseBraun

I am searching for my grandmother Olga Roth Wurfel LB9N-Y5K (Olga Rott).

She was born in Kronau Jan 16, 1897 to Jakob Roth and Kathrina Neuberg.

Jakob may have been from Ciobancuiusu, Dobrudscha. Katharina Neuberg(er?) died in Mangalia Romania in 1930's.

I have not been able to find her birth/baptism record. She may have ben Lutheran.

Thank you
