According to their attorney, Andrew Stollman, Briana Nelson, 31, and her 11-year-old niece, Victoria, have claim to some of the late music icon's following his death on April 21 at age 57.
The two claim to be related to Prince's half-brother, Duane Nelson Sr., Stollman tells ET. Briana, who resides in Milwaukee, Wisconsin, is Duane's daughter, while Victoria, who lives in Minnesota, is his granddaughter via his son, Duane Jr. Both Duane Jr. and Duane Sr. are no longer living.
Though Prince's estate is reportedly worth around $300 million, Stollman tells ET that the inheritance that Briana and Victoria are looking to get is not in the millions.
Since a judge determined in late April that Prince did not leave a will
, a trust company was appointed as special administrator of his estate, per the request of his sister, Tyka Nelson.
Last month, Carlin Q. Williams of Kansas City, Missouri, filed a paternity claim
against the estate claiming he is the deceased musician's son.
Tyka says she and Prince's five surviving half-siblings -- John Nelson, Norrine Nelson, Sharon Nelson, Alfred Jackson and Omarr Bake -- "remain united," though they have faced off in court
over Prince's net worth.
On Sunday, the "Purple Rain" singer was remembered at a private funeral
at Jehovah's Witness Kingdom Hall in Minnetonka, Minnesota.
