Who is Margareta? But yes, the Palace refers to her great-aunts as Princess Esmeralda and Princess Marie-Christine. However, Esmeralda (who lives in England) and Marie-Christine (who lives in the United States) use their husbands' surnames in their private lives.
Her mother Princess Astrid, who as I said above is known officially as HRH Princess Astrid
, and who lives in Belgium, does not use her husband's surname and signs her correspondence "Astrid of Belgium".
