2) Inspired by the placename Mecca (see below, less likely) 
The explanation of the origin and meaning (2) has its roots in the 17th century: During the "Turkish Abductions" (Icelandic Tyrkjaránið), a series of slave raids by Ottoman pirates that took place in Iceland in the summer of 1627, pirates from Algeria and Morocco raided the village of Grindavík on the southwestern coast, Berufjörður and Breiðdalur in the Eastern Region (the East Fjords), and Vestmannaeyjar (islands off the south coast). About 400 Icelandic prisoners were taken and sold into slavery on the Barbary Coast. Very few of them returned to Iceland. It is said that one woman who returned from slavery named her daughter after a good and caring mistress back in Algeria. Her name derived from the placename Mecca.
