On early 20th century maps, Sallynoggin and Glenageary are indicated as being the same place, however, with the development of the local authority housing estate on the Townlands of Honeypark and Thomastown, Sallynoggin became a distinct area. Up to 1994 the boundary of Dún Laoghaire Borough Corporation left a section of the local authority housing outside the Dún Laoghaire area mainly Pearse Villas and a part of Pearse Street which were in the Dublin County Council area. With the formation of Dún Laoghaire, Rathdown County Council in 1994 the entire area of Sallynoggin, Rochestown, and surrounding areas were included in the new county.
Etymology
The Irish Placenames Commission has researched the origin and meaning of Sallynoggin as a placename. In fact, the name is not Irish at all but English deriving from the "sally noggins" which referred to old timber-frame houses that were known to be situated there. The modern Irish word for noggin is the phonetic "naigín" hence "An Naigín" as it is commonly called. More than likely this is a placename of English origin. Examples of the word naggin or noggin were collected in Hiberno-English, meaning ‘a wooden vessel’. The origin of the word is unclear to lexicographers. The following meaning of the word noggin also appears in the English Dialect Dictionary, ‘the clay and sticks, or bricks used to fill the interstices of half-timbered houses’. This is a more likely explanation of ‘sallynoggins’; in other words, sally-rods may have been used in the construction of the houses.

The Catholic church is situated in the centre of the parish and was opened in 1955 and dedicated to Our Lady of Victories. Prior to the building of this church a small church dedicated to St. Kevin was located on the west side of Sallynoggin Road serving the village of Sallynoggin from 1927.
