what's the difference between mac and mc
Mac and Mc together A convention of sorting names with the Scottish and Irish patronymic prefixes Mac and Mc together persists in library science and archival practice. An example is from the Archives at the Yale University Beinecke Rare Book and Manuscript Library.[1] It is also applied in areas such as voter registration, where Mac and Mc names may be sorted together in a listing.[2] Technically this is a convention in collation.
