[General] all of who

I've got two questions about the text below:
1) Does it sound natural? If not, or if it's dated, could you please correct it?
2) Is all of who used in modern English the way it is used in the text?

My three boys are all very active and also very diverse. Matthew is a very bright and talented musician; he loves to play the piano. Peter is a very friendly, creative boy who likes to dance. Alex is the easy-going youngest who loves whatever is happening as long as he is involved. All of the boys love sports of all kinds. As well as all the family, they are looking forward to your visit in September. To add to the confusion, we also have two dogs (Carley and Solomon) and two cats (Marmaduke and Alpha), all of who are friendly and love people.

I want native speakers to say whether the whole text sounds natural and whether the "all of who" is used properly.

Grammatically, it should be "all of whom."

But there is no need for the "all of" at all. We have two cats and two dogs who are friendly and love people.

Hello.
I feel something is wrong with 'As well as all the family, they are looking forward to your visit in September.'
Is it not 'They as well as the rest of the/my family are looking ...'?

(Edit) I think it is a typo- 'Peter is a fery [I suppose it's 'very' that you meant] friendly ...'

Is it simpler to say 'My whole family is looking ...'?

Not a teacher.

Yes, but there might be some reason that englishhobby is using 'as well as' there. (It might be better for us to make as few amendments as possible to the original.)

Matthew, it's time to ask you again to refrain from making suggestions or proposing alternative versions until teachers or native speakers have had the opportunity to answer. The thread becomes very cluttered when we need to consider your comments as well as the OP's question.

I have deleted the above posts to tidy up the thread.

You can ask supplementary questions later.

I am not a teacher.

I agree that this sounds wrong.

To keep it conversational, I would suggest 'Together with/along with the rest of the family...'

Okay, that's where it gets weird. Try something like:
Or:

And if you want to add a little humor you might say:

I would make that two sentences, thus:
Finished!

'Matthew is a very bright and talented musician, Peter is a very friendly creative boy, Alex is the easy-going youngest, all of whom love sports of all kinds.'
Is 'all of whom' used properly here?

Not a teacher.

No.
And they all love....

Is 'all of whom' an unnatural expression which should be avoided?

Hello,
why we can't use "all of them" here? What is difference between "all of them" and "all of whom"?

No, it's fine to use in a letter or email. It's not common in conversation.

The difference is that 'which' is a relative pronoun and remains part of the sentence.

You can use either

'I have two dogs and a cat, all of whom are friendly' or

'I have two dogs and a cat. All of them are friendly'.

I suppose it's correct. Here's what SoothingDave wrote above:

The problem here is the sentence structure. It begins with three independent clauses separated by commas. This is a problem in itself. Then it attaches a relative clause to one that is supposed to refer to the subjects of all the independent clauses. That does not work. Relative clauses in one clause don't normally refer back to other independent clauses.

The rule is: Ron didn't suggest it, so it's not a good idea.
