Julianstown was the seat of the Moore family who lived in Julianstown House and occupied the land that now contains the townland of Julianstown West. Taylor and Skinner's 1783 Road Map of Ireland refers to the Moore seat and also shows the Church of Ireland Church which still stands today. There is little evidence of any other habitation at that time. Taylor and Skinner also show the milestone in the centre of the village marking 20 Irish miles to Dublin. This milestone can still be seen today. There is further mention of William Moore in Lewis' Topographical Dictionary of Ireland (1837).
