This is a very unusual and interesting name, not the least because its origins are extremely hazy. The name seems to be "English" but is probably an Anglicized development of the French "Blase", but it may be Irish, and of habitational origin from the Blasket Isles off the Coast of kerry. This second conjecture has a measure of confirmation in the first recording as shown below, in that "Larkin" is also a West Coast Irish name which derives from O'Lorcain meaning "a fierce warrior". The "French" origin possibility is as a metonymic for a wordly wise person with Blasket(t) being a patronymic meaning "Little Blase" or "son of Blase". The name recording include James Blasket of finsbury on September 9th 1739, and John Blaskett who was christened at St. Martins in the Field, Westminster on June 14th 1749. The first recorded spelling of the family name is shown to be that of Mary Blasket, which was dated May 28th 1730, married John Larkins at the church of St. Edmund The Martyr, London, during the reign of King George 11, "The Last Soldier King", 1727 - 1760. Surnames became necessary when governments introduced personal taxation. In England this was known as Poll Tax. Throughout the centuries, surnames in every country have continued to "develop" often leading to astonishing variants of the original spelling.
