Twin babies of Denmark's Crown Princess Mary were christened at Holmen's Church in Copenhagen with Mary’s Australian family and friends as godparents. More than 300 well-wishers attended the baptism ceremony which was officiated by Bishop Erik Norman Svendsen.

The twins, Prince Vincent Frederik Minik Alexander and Princess Josephine Sophia Ivalo Mathilda are siblings for Prince Christian, 5, and Princess Isabella, 4. All four are Crown Princess Mary’s children to Crown Prince Frederik.

The six godparents to Prince Vincent included Mary's brother, John Stuart Donaldson. Josephine Rechner, Mary’s friend, and Patricia Bailey, Mary’s sister were godmothers to Princess Josephine.

In keeping with Danish royal tradition, the names of the new prince and princess have been kept secret since their birth. The children’s names, Minik and Ivalo, are Greenlandic names in honor of Denmark's autonomous territory. Sophia was taken from the name of the Queen Consort of Denmark, Ingrid Victoria Sofia Louise Margareta, who died in 2000. She is maternal grandmother of Princess Mary.

Prince Vincent wore a lace robe with bonnet which was made for the 1870 christening of Prince Christian. The Brussel’s robe has also been worn by his siblings, father and grandmother, Queen Margrethe. On the other hand, Princess Josephine's robe was a gift to Queen Ingrid on her birth in 1940. The twins' maternal grandfather was also present at Thursdays christening.

Mary and Frederik met in Sydney in 2000 and got married later. With this, Australians’ level of interest in the Danish royals has increased.

According to the Hobart Mercury newspaper, the Tasmanian government plans to send christening gifts to Denmark. Tasmanian children's books will be shipped to Copenhagen inside handcrafted timber boxes.
