Leixlip Villas is listed as having 4 houses in the 1911 census.  It does not appear in 1901, nor on any known lists or directories.

It is likely that this is confused with Leixfort Villas, which had 4 houses in the 1908 map and was not listed in the census

The map shows the position of Leixfort Villas, on Corrig Avenue
