The Isle of Man has an interesting and rich history. This is in no small part due to the fact that the island is uniquely situated between the coasts of Ireland, Scotland, England and Wales -- stand on its highest point, Snaefell, and on a clear day you can see all four countries.
Between the 5th and 8th centuries the Island came under the sovereignty of various Welsh kings whose reign extended to the Isle of Man. They were styled King of Ynys Manaw, the Welsh name for the Island. The 8th century saw Viking invasion and rule, establishing a Norse Kingdom of Mann and the Isles, and a Manx parliament. Scandinavian rule came to an end in 1265, when the island became caught up in a battle between Scotland and England; control passing between the two. By the 15th century, sovereignty was in the hands of the English Crown, and the Island was governed by hereditary Lordship. The Island now has its own democratic parliament.
The native language, Manx, was spoken up until the 1970s, when sadly its last native speaker died. It is now beginning to see some signs of revival. Manx, or Manx Gaelic, is a Goidelic language, along with Scots Gaelic and Irish. These Goidelic languages, combined with the Brytholic (Welsh, Cornish, Breton) make up the main Celtic languages.
Names in the Isle of Man therefore, are a rich mixture of English, Irish, Scottish, Welsh and Norse influences as well as uniquely Manx creations. Many are the popular names you would expect (Oliver, Jack, Olivia, Ruby...) but mixed in are some of the Island's own gems.
The names below I have sourced from historical documents (census and manorial rolls), scholarly texts on the subject, and from birth announcements from the Isle of Man. Names that have been found in birth announcements from the last five years have been underlined.

Africa, Aufrica, Averick, Aurick, Affric - Many noble medieval women of Mann (and others in Ireland and Scotland) bore this name, including the wife and also a daughter of King Olave I; the daughter of King Godred II; and Aufrica de Connaught, heiress of Mann. Some scholars, such as O'Corrain & Maguire, attribute the name as a borrowing of "Africa". Others, such as Macbain and W.J.Watson derive its meaning from the Gaelic ath, an intensifying prefix, and breac "dappled, freckled." Given that Africa and Aufrica appear as Latinised forms of Affric -- and given the archetypal freckled complexion of the Gaels -- the latter explanation has most weight.

Blaanid - A diminutive of blaa "flower". This is the name of a legendary Manx princess, cognate with the Irish Blathnat.
