Forlong

We have no date of birth for Forlong, but he is described as 'old and grey-bearded' at the time of the Battle of the Pelennor in III 3019 (The Return of the King V 1, Minas Tirith). This is not enormously informative, but it seems reasonable to say that he was born at least half a century before the War of the Ring (that is, very roughly the year III 2960). Depending on the extent of his Dúnedain ancestry (which would grant him a much longer lifespan) he might conceivably have been born decades earlier than this.

As Lord of Lossarnach, a region close to Minas Tirith and the heartland of Gondor, it would be natural to assume that Forlong was descended from the Dúnedain who founded the land. His name, however, comes from traditions that dated back to the time before the settlement of the Dúnedain, and might be taken to imply that he was descended, at least in part, from the original inhabitants of Gondor's lands.

Forlong's name is explicitly uninterpretable, coming from the pre-Númenórean tongue used during the Second Age in the lands that would later become Gondor. Before Tolkien used the name for this Lord of Lossarnach, he briefly considered it as one of the aliases of Gandalf in different parts of Middle-earth. At one point Gandalf's name in the south would have been Forlong, before that was amended to Fornold, and ultimately became the quite different Incánus in the published book. Nonetheless the name Forlong survived in the person of Forlong the Fat, Lord of Lossarnach.
