English and Irish
English and Irish : apparently a topographic name from Middle English furlong ‘length of a field’ (from Old English furh ‘furrow’ + lang ‘long’), the technical term for the block of strips owned by several different persons which formed the unit of cultivation in the medieval open-field system of farming, or a habitational name from a minor place named with this word, such as Furlong in Devon or Shropshire. The surname is now chiefly common in Ireland, where a family of this name settled at the end of the 13th century.Possibly an Americanized form of French Ferland.

Surname or Lastname

English : variant of Black 1, meaning ‘swarthy’ or ‘dark-haired’, from a byform of the Old English adjective blæc, blac ‘black’, with change of vowel length.English : nickname from Old English blÄc ‘wan’, ‘pale’, ‘white’, ‘fair’. In Middle English the two words blac and blÄc, with opposite meanings, fell together as Middle English blake. In the absence of independent evidence as to whether the person referred to was dark or fair, it is now impossible to tell which sense was originally meant.Irish : Anglicized form of Gaelic Ó Bláthmhaic ‘descendant of Bláthmhac’, a personal name from bláth ‘flower’, ‘blossom’, ‘fame’, ‘prosperity’ + mac ‘son’. In some instances, however, the Irish name is derived from Old English blæc ‘dark’, ‘swarthy’, as in 1 above. Many bearers are descended from Richard Caddell, nicknamed le blac, sheriff of Connacht in the early 14th century. The English name has been Gaelicized de Bláca.
