Gift not marked as received (user changed name?)

A name change should not affect that.
When I got my name change it didn't at all affect any of the feedback from the gifts I've gotten or the gifts I've sent.

Better do a screenshot of his inventory, that might help when you will be talking with SG support. It will be your proof that you sended the game.

You will need a picture of the trade history to prove he accepted the gift. That is all needed i guess.

Well checking profiles I found him and if it's "him", rush to a screenshot, he has a lot of games not claimed in his inventory and one is a "The Ships - Gift"

By the way, he hasn't any "The Ship" activated in his account.

Ah okay, thanks. Just seem odd he's name didn't update on steamgifts. I took some screen shots in case, shame can't take a screen shot of chat history too. I know he has another account as asked me to send it to that one after i already send it to him
I'll see what's up when he's next on line, otherwise i might have to see SG support

seems odd to be able to change it days after already confirming it too
