Complicated problem !!!

Generally speaking, a person cannot change names on citizenship papers from any country without having some legal right or record to the changed name when it is different from the name on the birth document. For example, the US allows name changes as a part of the naturalization process, but notates naturalization certificates with the legend showing the change of name. I would assume that there is some record in the country of your second citizenship which accounts for that country's acceptance of a different first name. You will need to obtain that record. Then you can present that with your original certificate of birth. Insofar as translations are concerned, you do not have to go to your consulate of your original country. You only need to go to a competent translator who can verify fluency in the home language and attest to the accuracy of the translation.
