Mo Chroí (sounds like McCree), meaning: my heart
Chroí comes from Old Irish crid-, meaning “heart.” Macushla Machree entered English in the first half of the 19th century. Macushla is a phonetic Irish Gaelic mo chuisle, “my pulse,” or more romantically, “my heartbeat, my sweetheart, darling.” In full, a chuisle mo chroí, literally, “pulse of my heart.”
