HELLO!
I AM SILVIU MUSAT FROM ROMANIA.
i DO NOT KNOW ABOUT YOUR RELATIVES BUT , I KNOW THAT " METRU" ITS CORRECTLY MITRU AND ITS A NICKNAME FOR DUMITRU (DU-MITRU).
WE HAVE A LOT OF BOTA IN ROMANIA BUT I DONT KNOW ANITHING ABOUT YOUR RELATIVES.
A LITTLE ADVICE: TRY TO FIND A PHONE LIST TO THE SUCEAVA COUNTY OF ROMANIA
AND SEARCH FOR BOTA

GOOD LUCK
