First found in Cheshire where they were seated from very ancient times, some say well before the Norman Conquest and the arrival of Duke William at Hastings in 1066 A.D.

Some of the first settlers of this name or some of its variants were: John Leach arrived in the Barbados in 1679, with his servants; Lawrence Leach settled in Salem in 1628; Margaret Leach settled in Boston in 1635; Rebecca Leach settled in Virginia in 1639.
