Birth parents ?

Hi my name is Vrettoula Chirva. My name before marriage was PANARETOS. My father (who adopted me) was Zaxarias Panaretos and my mother (An australian) is Theodora Panaretos. My papou and giagia were Vretto and Eleni Paretos and are buried in Potamo, where we have our family home. I have been in a desperate search for my birth mother or father for more than 40 years. Hopefully someone maybe able to shed some light on the situation. My birth date is 16th June 1956. My parents travelled to Greece to adopt me.

Thank you so much
