A son has the same surname as his father. A female's surname replaces "Ó" with Ní (reduced from "Iníon Uí" – "daughter of descendant of") and "Mac" with Nic (reduced from "Iníon Mhic" – "daughter of the son of"); in both cases the following name undergoes lenition. However, if the second part of the surname begins with the letter "C" or "G", it is not lenited after "Nic". Thus the daughter of a man named Ó Dónaill has the surname "Ní Dhónaill"; the daughter of a man named Mac Siúrtáin has the surname "Nic Siúrtáin". When anglicised, the name can remain O' or Mac, regardless of gender.
