As early as 1943, Elias Wessén convincingly demonstrated that the sequence in question cannot be read as a carver's signature.
U 203 was raised by Ale (or Alle) in memory of his son Ulv, “father to Frögärd in Väsby”.
According to this inscription, Ale (Alle) received a share of Canute the Great’s Danegeld in 1017.
Thus, Frögärd was probably a member of a wealthy family and the only beneficiary of her father's and grandfather's inheritance.
Birgit Sawyer suggests that Ale's (Alle's) purpose with U 203 could have been to take care of his underage granddaughter's inheritance.
