I'm starting to scrape the barrels when it comes to Elven lineages - apologies to all the Leggy fangurls out there! This is Oropher's family - the lineage of the rulers of Mirkwood. All we have from canon is Oropher, Thranduil and Legolas, and no designs for any of them, so this really is more fantasy than fact.
Top right is Oropher, whose design will relate back to those of Elwë and as those of the Nandor (when that page is done). His wife is Mirafin, in the bottom left. Her identity and racial affiliate is officially unknown, so I've given her something different to show she's not from any of the main families I've done before. Then below her is Thranduil. To Thranduil's right is Santhar, his wife, and below them, Legolas, whose woodland colours are diluted slightly by some golden yellow and the light blue from his mother.
The predominant colours here are obviously greens and browns, symbolising their Sindar and Sylvan nature, and the same colour scheme will go forward to the Nandor page.
