Oh [name]Tyne[/name] [name]William[/name] [name]Henry[/name] is beautiful! [name]Stellan[/name] is quite handsome too, but not as unusual as [name]Tyne[/name]. I also swoon over [name]Hadrian[/name].
[name]Tyne[/name]! It sounds modern, yet sort of wistful at the same time. And it’s close to the word tine, which is such a neat little word for the prong of a fork. I know that may not be a real draw for you, but I love words that have such a precise place in the world. Think of the tattoo possibilities! If my name were [name]Tyne[/name] I’d totally get a fork tattooed on my arm. Maybe a fork stabbed into a map of Northumberland! 
I think [name]Tyne[/name] [name]William[/name] [name]Henry[/name] would be the boldest - and most interesting- choice for you. I’ve seen so many Mc/[name]Mac[/name] names with such terrible spellings that I really don’t find them appealing for either gender. The trendy [name]Kylan[/name] isn’t Irish and the similar name of Cailín means “girl” so I don’t think it’s good choice either. [name]Do[/name] you like [name]Tynan[/name] (TIE-nin), an Irish surname that means “dark”? It incorporates part of [name]Tyne[/name], part of [name]Keegan[/name]/[name]Stellan[/name] and your Irish heritage. 
I really like [name]Tyne[/name] ALOT. Given, I’m not from your neck of the woods, so I can’t speak to the negative association that some posters mentioned - but it sounds like it’s not something you’re worried about. Anyway, it sounds plenty masculine even without [name]William[/name] and [name]Henry[/name] to follow it up, but all together WOW. [name]Love[/name] it for you.
The [name]James[/name] connection is because the Football stadium in Newcastle is called St [name]James[/name] [name]Park[/name], some kids get named [name]James[/name] just because their parents are obsessed with Newcastle United Football Club, a child who is friends with my little cousin is called [name]James[/name] Shearer [name]Tyne[/name] because of there connections with the team (Shearer is the last name of a well known Newcastle football player).
I really like [name]Mackenzie[/name] [name]William[/name]. I only know two [name]Mackenzie[/name]'s and both are boys so I feel it’s more masculine.
