Princess Macha was the daughter of High King Lugh the Seafarer, one of the more illustrious High Kings of the Selkie, who ruled from 76 BCE to 30 BCE. Princess Macha is mostly known due to her beauty, quite a few songs are sung about that, her sharp tongue and her mind, which secured the position of her father in troubled times between 49 BCE to 45 BCE.
Born as sixth of nine children of High King Lugh the Seafarer and High Queen Aeoifa of Teanga, Macha had to compete for her place with her siblings, especially with Prince Nuada and with Princess Tailtiu, who took the position of a mother in place of Aeoifa, as she died in 64 BCE (Macha was of Six Springs at the time).

Macha was known as a person, who liked the Spiorad Ainmhithe,
