Mckeith Family History
Mckeith Surname Meaning
From the male given name Keith, which is originally from a Scottish locative surname for which see Keith. Although Mac may have been used with some non-Gaelic personal names, compare McAndie, this is the less likely explanation.
From Mac Shìthich 'son of Sìtheach', a personal name meaning 'enchanted' or 'peaceful', or, as suggested by Black, a Gaelic euphemism for 'wolf'.
Compare Irish Sheehy.
