the name of one of them

[Liza]

Hi,

Sorry, I got stuck now with a quite simple sentence. Could you help me how to continue this:'I have two sons.

e,g,
The name of one of them is Adam. (?)
OR:
One of their name is Adam. (?)
OR:
?

I know that 'One of them is called Adam' - would be OK, but if I'd like to use a possessive structure, what is the correct way? The two 'of' looks so strange in the first sentence.

Thanks a lot.

Hi Liza,

How about this:

I have two sons one of whom is Adam.

Dear Torsten,

Thank you for your asnwer.

Yes, I'm sure that there are other ways to avoid my original sentence and to express a similar meaning. But if I'd like to insist on a possessive structure similar (mentioning the word 'name' in it) , than what is the grammatical way to say it?

Thanks again

[Torsten]

How about "My younger son's name is Adam."

These are OK too:

The name of one of them is Adam.
One of their names is Adam.
