Boys names: 2 syllables, 2nd syllable begins with TH?

[The8thMonth]

I'm expecting my 3rd boy and have run out of ideas for boys names that fit the criteria as in the title...

My first two sons are Arthur and Nathan.

Others I've thought of for boy 3 include:

Matthew
Ethan
Jethro

Can anyone help me with any others?

I can only find more unusual names which fit exactly.

Luther
Cuthbert
Swithin
Xanthus
Rothwell
Waltham
Gethin

Not quite all your criteria but similar...

Matthias
Theo
Timothy
Seth
Gareth
Ellsworth
Heath
Griffith
Jareth
Thaddeus
Thor
Thurlow

Thank you so much!! Those are some I've not come across yet. I'll definitely be adding them to my list... I'm not too bothered about unusual names, but we'll see what the husband thinks.

Anthony sort of works!

Ooh I like Gethin from the list above.

Thank you all! I too liked Gethin....

Arthur, Nathan and...

Mathias
Bartholomew
Jotham
Balthazar
Gunther
Haytham
Jephthah
Lothar
Matheo
Mathis
Otho
Othmar
Walther

Thaddeus
Seth
Heath
Japheth
Braith
Daveth
Griffith
Jarlath
Leith
Thane
Theodore
Timothy

Matthew.
Not Gethin. wouldn't it be awful if he married a Fatima LOL

I love Gethin and it sounds great with your other dcs

Do they really have to be named according to a scheme?

Thank you everyone for all the great suggestions!

No, they don't have to all be named to a scheme but if we found a name we liked and it suited, then we would.

Gethin is a lovely name, but very classically Welsh, to the point that I’d tend to assume any Gethin had strong Welsh roots. Not a value judgement just a point of consideration when choosing it as a name for a person!

I think Matthew works best with your other names. Ethan is too like Nathan as Jonathan would be too.
Timothy is good too.

Wouldn't do Ethan as it's too close to nathan. How about

Henry
Albert
Edward
Stanley
William
Matthew
Andrew
Joshua
Daniel
Michael
