Chestnut Family History
Chestnut Name Meaning
Scottish (Renfrewshire and Lanarkshire) and northern Irish: altered form of Chesney shortened from McChesney . Its assimilation to the English word chestnut is due to folk etymology the word itself being first recorded in 1519. The surname was probably taken to Ireland at the time of the 17th-century Plantation of Ulster. English (Norfolk): probably a variant of Chestney (see Chaney ) altered by folk etymological association with the word chestnut.
