[name]Dewi[/name] is not a misspelling of [name]Dewey[/name]. They are both welsh versions of [name]David[/name], but [name]Dewey[/name] is pronounced Doo-ee, and [name]Dewi[/name] is pronounced Dew-ee. I live in [name]Wales[/name] so [name]Dewi[/name] is a normal name where I live.
In my American accent, Doo - ee and Dew - ee are pronounced the same. That said, I like [name]Dewi[/name] [name]John[/name], although [name]Dewi[/name] could sound like an adjective. Like [name]John[/name] is covered in Dew. That could just be me though!
I think it works as long as your last name is more than one syllable.
I believe the distinction, for those like me with yod-dropped dialects, is doo-ee vs. dyoo-ee, no? We would never say Dyoo-ee, but we can imagine it when it’s spelled out that way.
Either way, [name]Dewey[/name] [name]John[/name] or [name]Dewi[/name] [name]John[/name] are fine I suppose : D. I’m outside of Welsh culture so it’s really hard to say. The flow is fine, particularly, as above, if you have a longer surname.
Its kind of strange …I don’t like [name]Dewey[/name] or [name]David[/name]…so not my thing
I immediately think of [name]John[/name] [name]Dewey[/name], the philosopher. I mean, [name]John[/name] [name]Dewey[/name] was great, but is it a conscious nod to him? Is [name]John[/name] a family name? Any interest in [name]James[/name], or [name]Jonathan[/name]?
I am curious to know why [name]Dewey[/name] and [name]Dewi[/name] are pronounced differently in [name]Wales[/name]. Is it just a linguistic quirk?
That asked, I like [name]Dewi[/name]. [name]Dewey[/name] or [name]Dewi[/name] is my favorite nickname for [name]David[/name], but I don’t think it would work here in the U.S. Since you’re in [name]Wales[/name], where it’s normal–go for it!
I like [name]Dewi[/name] [name]John[/name]–[name]John[/name] is a solid, classic choice that grounds the lighter-sounding [name]Dewi[/name]–though [name]Dewi[/name] does sound a bit like an adjective here, as a pp mentioned. I also tend to prefer longer middle names with shorter firsts:
[name]Dewi[/name] [name]Nicodemus[/name] (I love [name]Nicodemus[/name] as a middle, especially with 2-syllable, ending-in-EE-sound names! It would be perfect with [name]Dewi[/name].)
[name]Dewi[/name] [name]Jonathan[/name] (as a pp suggested)
[name]Dewi[/name] [name]Tobias[/name] (one of my favorites)
[name]Dewi[/name] [name]Jeremiah[/name]
[name]Dewi[/name] [name]Matthias[/name]
Etc…
Best wishes!
I would pronounce Doo-ee and Dew-ee the same. I dislike it. The only relation I have with the name is my neighbor who recently died was Mr. [name]Dewey[/name] (his surname), an old friend of mine named her dog [name]Dewey[/name], and I vacationed as a child in [name]Dewey[/name] [name]Beach[/name], DE. It just doesn’t scream first name to me, and I don’t particularly like the sound.
Is your question do we think that [name]Dewi[/name] [name]John[/name] is a combo that flows well together then the answer is Yes. I can differentiate between the sounds of [name]Dewey[/name] and [name]Dewi[/name].
I do think [name]Dewi[/name] sounds cutesy, a little nicknamey. I love the name [name]David[/name] or the Welsh equivalent so that would be the way I would go.

[name]Dewi[/name] isn’t pronounced Dew-ee or Doo-ee. It is pronounced as follows: Dewi pronunciation: How to pronounce Dewi in Welsh, Indonesian
The closest I can come to transcribing it is: DARE-wee or DEH-wee.
Hopefully this clears up why [name]Dewey[/name] and [name]Dewi[/name] sound nothing alike in [name]Wales[/name]!
[name]Hope[/name] this helps! 
[name]Dewi[/name] [name]John[/name] sounds nice.
[name]Just[/name] has me thinking [name]Dewey[/name], Hewey and Louey.
[name]Dewi[/name] [name]John[/name] is a fine and handsome combo. It certainly wouldn’t be too “out there” for [name]Wales[/name].
St [name]David[/name] is the patron saint of [name]Wales[/name], and is called “[name]Dewi[/name] Sant.” St [name]David[/name]'s Cathedral is the national cathedral, many churches are dedicated to him, etc. So it might strike many as a very nationalistic name, or perhaps a strongly religious name.
I went to school (in Los [name]Angeles[/name]) with a [name]Dewey[/name], and he was always teased for his name (doo-doo etc.)…apparently his parents had allowed his big sister to name him (maybe she got it from [name]Donald[/name] Duck’s nephew)! But given the different pronunciation in [name]Wales[/name], I guess the name wouldn’t be a problem there.
I’m reasearching [name]John[/name] [name]Dewey[/name] for an education psychology course right now so that’s what I immediately thought of. [name]Dewi[/name] [name]John[/name] is all right, I think [name]John[/name] is quite handsome as a middle name but I’ve never been keen on [name]Dewey[/name]… and even though the pronunciation is different, I’m not sure I care for [name]Dewi[/name] much more. It’s interesting, though.
I agree with the PP, I pronounce it Dew-ee, though I’m an American as well. I am not a fan of it, it strangely makes me think of doodie (another name for feces), no offense but that’s my opinion. I do like [name]David[/name] and [name]John[/name], however.
[name]Dewi[/name] is ok , I know how to pronounce it the Welsh way… But there are much nicer Welsh names to choose from .
Thanks for the Forvo link, lilou. The Welsh pronunciation leaves little room for the adjective problem (dewy [name]John[/name].)
[name]Dewi[/name] [name]John[/name] sounds cutesy to me.
