Tahj/Taj: Hindu name meaning 'crown' (the Taj Mahal is a well-known palace) Tarik/Tyrek/Tyreke/Tyrique: all spelling variations of Tariq
Tavian/Tavion: 3 possibilities: 1) Irish, from the word teeve , meaning 'hillside' 2) Latin, meaning 'eighth' 3) Scottish, meaning 'twin', like Tavio
Tevin: either African boy name or a variation of the Irish Tavion (thus meaning 'hillside'); one site also said it was a form of Kevin, but i don't take that seriously)
Trae/Tre: yes, i also think a form of Trey/Tray, meaning 'third born' Travon/Trevin/Trevion/Trevon/Treyvon: either form of Trevor or abbreviation of Trevelyan, meaning 'fair town' Trever: when English, it's a form of Trevor; when origin French, it's a variant on the Old French name Travis
Treyton: variants include Trayton, Traton, Tratton and Tritten (as surnames) and the meaning is 'town full of trees' (from a placename indeed)
Tyquan: seems to me as a made-up name or else i don't know Tyree: from a Gaelic word meaning 'island dweller' (also the name of an island for the coast of Scotland) Tyreese/Tyrese: see the database for Tyrese Tyron: yes, presumably a form of Tyrone Tyshawn: apparently, Tyshan, Tyshaun, Tyshawn and Tysean are surnames, but probably a combination of Ty and various forms of Sean
Sincere: from the Latin word sincerus , meaning 'honest, true', but also 'not died (painted)', 'natural', 'pure', 'unmixed'.
Stone: you have to see it like this: the meaning of this name is more meant to be the characteristics of the object, what it symbolizes, in this case it could either mean 'steadiness', 'persistence' or 'strength, power'.
Talon: the French word talon means 'heel' (like Achilles' heel), the English word talon means 'claw'. I think it is an English name. I also saw a site translating the name as 'sharp'. This is a more non-literal translation of 'claw' (claws are sharp).
