About Prince Vincent of Denmark
Prince Vincent of Denmark, Count of Monpezat (Vincent Frederik Minik Alexander; born 8 January 2011) is a member of the Danish royal family. He is the third child and younger son of King Frederik X and Queen Mary, the sixth grandchild and youngest grandson of Queen Margrethe II and Prince Henrik, and the older twin brother of Princess Josephine. Vincent is third in line to the Danish throne, after his older brother, Crown Prince Christian, and older sister, Princess Isabella. == Birth and early life == Vincent was born on 8 January 2011 at Rigshospitalet, the Copenhagen University Hospital, in Copenhagen, at 10:30 am local time, 26 minutes before his twin sister. Shortly after the birth, while speaking to the press, the Crown Prince joked about calling his newborn son Elvis, as the twins share a birthday with Elvis Presley. At noon on 8 January, a 21-gun salute was fired from the Sixtus Battery at Holmen Naval Base in the Port of Copenhagen and from Kronborg Castle in Elsinore in North Zealand to mark the arrival of the royal children. Vincent and his sister were baptised by the royal confessor, the Bishop of Copenhagen Erik Norman Svendsen, on 14 April at the Church of Holmen in central Copenhagen. The twins were baptised at the royal baptismal font which has been used for the baptism of royal children in Denmark since 1671. Prince Vincent wore the royal christening gown which was made for his great-great-grandfather, King Christian X, in 1870, while his sister wore a gown found among Queen Ingrid's belongings. His name was announced as Vincent Frederik Minik Alexander.
