===Love life===
Fionn met his most famous wife, [[Sadhbh]], when he was out hunting. She had been turned into a [[deer]] by a druid, [[Fear Doirich]], whom she had refused to marry. Fionn's [[Irish wolfhound|hounds]], [[Bran and Sceólang]], born of a human enchanted into the form of a hound, recognised her as human, and Fionn brought her home. She transformed back into a woman the moment she set foot on Fionn's land, as this was the one place she could regain her true form. She and Fionn married and she was soon pregnant. When Fionn was away defending his country, Fear Doirich (literally meaning Dark Man) returned and turned her back into a deer, whereupon she vanished. Fionn spent years searching for her, but to no avail. Bran and Sceólang, again hunting, found her son, [[Oisín]], in the form of a fawn; he transformed into a child, and went on to be one of the greatest of the Fianna.

In ''[[The Pursuit of Diarmuid and Gráinne]]'' the High King [[Cormac mac Airt]] promises the aging Fionn his daughter [[Gráinne]], but at the wedding feast Gráinne falls for one of the Fianna, [[Diarmuid Ua Duibhne]], noted for his beauty. She forces him to run away with her and Fionn pursues them. The lovers are helped by the Fianna, and by Diarmuid's foster-father, the god [[Aengus]]. Eventually Fionn makes his peace with the couple. Years later, however, Fionn invites Diarmuid on a boar hunt, and Diarmuid is gored. Water drunk from Fionn's hands has the power of healing, but each time Fionn gathers water he lets it run through his fingers before he gets back to Diarmuid. His grandson [[Oscar (Irish mythology)|Oscar]] shames Fionn, but when he finally returns with water it is too late; Diarmuid has died.

===Death===
According to the most popular account of Fionn's death, he is not dead at all, rather, he [[King asleep in mountain|sleeps in a cave]], surrounded by the Fianna. One day he will awake and defend Ireland in the hour of her greatest need. In one account, it is said that he will arise when the [[Dord (instrument)|Dord]] Fiann, the hunting horn of the Fianna, is sounded three times, and he will be as strong and as well as he ever was.<ref>{{cite journal | journal = Journal of the Cork Historical and Archaeological Society | publisher = Cork Historical and Archaeological Society | series = 2 | volume = II | first = J.F. | last = Lynch | date = 1896 | title = The Legend of Birdhill | page = 188 }}</ref>
