Osman is the Turkish and Kurdish form of Uthman, an Arabic male name meaning “baby bustard” (bustards are large terrestrial birds that live in dry grasslands and steppes). Osman I was the founder of the Ottoman Empire.
Osman is also a surname- a Turkish surname originating from the given name, but it’s also an English surname, a variant of Anglo-Saxon Osmær meaning “god + fame”, made up of Old English os (god) and maer (fame), though it may also be a variant of Osmond “god + protection”.
Origin: Arabic; Proto-Indo-European
Meaning: “baby bustard”; also an English surname “god + fame” or “god + protection”
Owen is a male given name, an anglicized form of Welsh Owain, making it a cognate of Irish Eòghan, a name of uncertain meaning. The names have often been linked to the Ancient Greek name Eugenios (anglicized as Eugene meaning “well born”) and Eugene has been used to anglicize Owain and Eòghan, but it seems more likely that Owain is Celtic in origin, perhaps linked to Celtic *Esugenios meaning “good born”, combined of Proto-Celtic elements *esus (good) and *genos (born, birth; family), both deriving from a PIE origin.
Another intriguing theory behind the name Esugenios is that it consists of theonym Esus, the name of a Gaulish god, combined with *genos.
Another possible meaning attributed to Eòghan is “of the yew tree” or “born of the yew tree”. The yew tree was an important tree to the ancient Celts, symbolizing immortality (yew trees are long-lived) and rebirth. I’ve also seen it as possibly being derived from Welsh eoghunn meaning “youth”.
In Arthurian legend, Owain is also the name of one of the Knights of the Round Table (also known as Yvain in French). Owen is also a surname deriving from the given name, originally a patrynomic surname.
Meaning: “well born” or “good born”; “of the yew tree” or “born of the yew tree”, or possibly “youth”; perhaps a combination of Esus (a Gaulish god) combined with *genos
