I believe you are right. Probably your Maimon family was originally from Radauti-Prut, a small town in the Dorohoi district. The large Radauti (Bukovina) town became Romanian only after WWI. The Dorohoi Yizkor book mentions an "old" Maimon family from Radauti-Prut. There are also a couple of testimonies at Yad VaShem regarding people of Maimon family from Radauti-Prut.
