Flack Family History
Flack Name Meaning
English: probably from Middle English flack, flak ‘turf’, ‘sod’ (as found in the place name Flatmoor, in Cambridgeshire), and hence perhaps a metonymic occupational name for a turf cutter. North German: topographic name probably derived from a lost word denoting stagnant water.
