Ursula is the Latin diminutive of ursa (bear) — meaning "little bear." Saint Ursula was the legendary 4th-century princess martyred at Cologne with 11,000 virgin companions.
Ursula K. Le Guin (1929-2018) was the American science fiction novelist; Ursula Andress (born 1936) was the first Bond girl. Disney's Ursula is the iconic villain of The Little Mermaid.
Ursula reduces to one — the number of Latin little bear.
