700 people claim to be Prince's siblings as judge rules DNA samples be taken from the music legend's blood to verify claims

Morse Genealogical Services have sifted through more than 700 calls from people saying they are Prince's half-sibling since the icon's death last month at his Paisley Park estate in Minnesota. 



But only one looks likely to have a shot at proving she is actually related by blood to the singer, the man leading the official hunt for relatives told Daily Mail Online in an exclusive interview. Prince (left) is known to have one full-sister, Tyka Nelson (bottom right), and five half-brothers and sisters, Sharon (bottom left), Norrine (upper left) and John Nelson, Alfred Jackson (upper right) and Omarr Baker. Two other half-siblings, Duane and Lorna Nelson, have died. Daily Mail Online reported exclusively, Duane has a surviving teenage granddaughter, Victoria, who is entitled to his share, while Lorna died without having children.
