The ash tree was thought to have power over water. Consequently, Irish emigrants to America took pieces of the ash with them as a charm against drowning. The ash tree represents longevity, endurance and productivity. Along with an image of water on the bottom of the crest, the shape of the house crest resembles waves of water. Consequently, blue is House Ash's primary color. In addition, stars, which sailors used to navigate the seas, are found on House Ash's crest. The water pitcher, an element from the Marianist table, symbolizes the "living water" Christ gives us to help us toward our salvation.
