Can I and my family get an extension of stay in Thailand due to the war in Ukraine?

This is gonna be a difficult question, and the likely reply will be 'go talk to them', which I intend to do; will ask anyway for some ideas or insight.

So, there's myself, passport of Ukraine, entered 2 years ago visa exempt, after that had non-o volunteer (bleh) and have been on covid stamps since (about 9? of them I think).

There's my wife, passport of Russia, same visas/stamps.

Also got a 2.5 years old kid with Ukrainian passport (didn't do any extensions for him).

Now, we actually did plan to go back to Ukraine before our current extension runs out, but obviously this is no longer possible because of the war. I do have a letter from the embassy stating that the return to Ukraine is not possible because of the war and asking for assistance.

The two questions are:

- will they (Koh Samui immigration) make an exception for myself based on the embassy letter, despite me having a non-o before?

- is there any way to convince them to do the same for my wife, who despite having a Russian passport, obviously lived together with us in Ukraine (having a Ukrainian husband and a Ukrainian child). Official translation of a marriage certificate perhaps - would that do any good?

Thank you for your opinions.
