Is there an
Ian in the book that this woman could be said to be "serving"? Perhaps the author isn't being literal but is making a reference to the character Leana's relationship with the character
Ian.
Actually this could make some sort of sense if Leana is actually a shortened form of her full name. Many Gaelic surnames starting with
Gill- go back to forms that meant "servant of" some saint or religious figure.
Gilchrist was "servant of
Christ" and Gilfillan "servant of St.
Faolan", for example. I have sometimes seen
Gillian (with a hard "g" sound) explained as a Scottish male name meaning "servant of St.
John". So perhaps the author is implying that the character Leana's full name is something like Gilleana or Gilliana.
