I’m very sorry for your loss

Any reason why in thai?

You can look at internet translators but they’re risky. Essentially, I think you need to speak to someone who reads thai – it’s not worth the mistake

Again, sorry for your loss.

This is quite a relevant subject for me as I have my mother’s name in Thai tattooed on my arm. I had it done in Thailand and checked it with some locals ;-). I’d be inclined to patronise a Thai restaurant and ask for a translation. Obviously this would need to be checked, but perhaps your relative would be able to help with that (non english-speaking thai people were able to verify that mine was correct by reading my tattoo phonetically).

Good luck with it.
