I am researching several ancestral lines in Mystras, including that of my maternal grandmother, Aggeliki Eftaxias. During my visit to the General State Archives office in Sparta in July 2014, I digitized several pages of the Mitroon Arrenon (Male Register) for this city. The earliest year in these registers is 1824. Interestingly, this is right in the midst of the Greek War of Independence (1821-1829).
The surnames below are extracted from the pages that I obtained, which is not the complete record. Villages included in these records are: Mystras, Vlachohori, Varsinikos, Pikoulianika, Parori, Katochora, Diaselos.
The Sparta Archives office can assist you with further research. The email address is: email@example.com. Maria Stellakou, Michalis Sovolos, and Pepi Gavala are exceptional archivists and dear friends.
