Gaelic surnames beginning with Mac- means "son" so any surname beginning with Mac- usually refers to the son of etc., etc. I don't know if there are any Irish surnames that derived from a woman's name- usually names come from the name of the father, an ancestor, or as an occupational name or a nickname for a particular characteristic (hair, color, complexion, facial feature). However, Ní/Nic is used to refer to women (ex.
Brigid Ní
Pádraig-
Brigid daughter of
Patrick), if that helps.
