Norman French diminutive of Aalis (see Alice) [1]. It was common in England, Scotland and France in the Middle Ages, and was later revived in England in the 20th century via Scotland. Unlike most other English names ending in son, it is not derived from a surname.
People with the name Tristina have a deep inner desire to use their abilities in leadership, and to have personal independence. They would rather focus on large, important issues, and delegate the details.
