What is "mccawley"

McCawley and MacCawley are surnames in the English language. The names are Anglicisations of several Gaelic-language surnames. There are several etymological origins for the names: all of which originated as patronyms in several Gaelic languages— Irish and Scottish Gaelic. Although the English-language surnames are ultimately derived from Gaelic patronyms, the English-language surnames, and the modern Gaelic-language forms do not refer to the actual name of the bearer's father or grandfather. The surnames are not very common.
