Lefnoreis is recorded as being the most important of the three castles in the parish of
Old Cumnock, the other two being
Borland Castle and
Terringzean Castle.
The spelling of the placename The name of the fortification is commonly recorded as variations of both Lefnoreis and Lochnorris with the former version more widely used on maps and many other variations in spelling and title, such as the Ward of Lefnorris, Lefnoreise, Tower of Leifnorris, Liffnoris, Leifnoreis
Castle of Lesno in 1654,
Lesnoris in 1685 and finally as
Lissnorris in 1747-1755. It is also recorded as
Craufurdstoun as is the near by
Terringzean Castle. Considerable confusion has arisen in the writing of the castle's name arising from the use of the
Long s to represent a lower case
s in documents until around 1800 in printed documents and well into the 19th century for written documents. The convention previously being to use a letter similar to an elongated
f, leading to a lower case
s being easily and often confused and interpreted as an
f. On the above mentioned maps this led to
Lissnorris for example apparently having the spelling
Liffnorris. An actual
f had a short horizontal stroke to differentiate it. The intended pronunciation of the name might therefore be closer to
Lesnories.
Ward It is unusual for the term
Ward to be applied to a fortification's name. In Scottish Law a
Ward is "
..the oldest form of feudal land tenure, viz. by military service, with various attendant rights and obligations, esp. that of the superior to uphold and draw the rents of the lands of a deceased vassal while the heir was uninfeft or remained a minor, as an equivalent for the loss of military services during such period, the usage being termed simple ward. Later commutation was admitted for a monetary payment in lieu of the drawing of rents." This implies that the use of the name
Ward only applied to periods in which the male heir was a minor, etc. ==Description of the castle and lands==
