The Old Norse male personal name Skarði was originally a byname from Old Norse skarði ‘notch, hack’. A few instances are recorded as a personal name in Norway from the eleventh century onwards. It is also found as a byname in Norway and Iceland and in some Swedish runic inscriptions in the form skarþi. Skarði is possibly found in a Danish place-name and a strong form of the name Skarth appears in Denmark in the fifteenth century. The personal name may also be the first element in Scartho, Lincolnshire.
