Notes

*1 Meaning ‘nickname,’ I think.

*2 The majority of names starting with Dubh or Duibh in Irish are derived from the adjective dubh, black; the second part of such names is usually speculative being often obsolete forenames [first names]. Similarly those beginning with Donn or Duinn are mainly from donn, brown.

Duff
As well as being a surname of the epithet {*1} type (dubh, black) Duff occurs as an abbreviated form of Duffin in Co. Wexford, of MacElduff in Co. Tyrone, and of Duffy in several counties. See Black.

The most numerous of the forms given above are Fee (in Fermanagh, Armagh and Cavan) and Foy (Cavan and north Connaght).
