Question about getting a new passport before applying for fiance visa

Sorry if I'm being dense and this has already been mentioned elsewhere, but I didn't find any exact mention of it in a search.  I think I remember something similar to it being mentioned, but couldn't find it for the life of me!

I just had a sudden thought when I realized that my name will legally be changing before I apply for my visa, so I'll be getting a new passport.

Will the stamps and stuff saying when I entered the UK and the US be in my new passport?  If not, do I need to provide something else proving I've been there and met my fiance and stuff?  I have my boarding passes, and credit card receipts from hotels.  Was just wondering whether it'd make a difference or not if I no longer had a passport that was stamped with entrance into the UK.

*Edit* Oho, the thing I saw was about tranferring FLR and ILR to a new passport, and it's stickied at the top of this section...that'd be the similar thing.  I'm so observant!     Oh well, it's not exactly the same, I guess, so might as well ask anyway!

Hi Candice.... When you get your new passport they will also return your old passport to you. You will want to bring your old passport with you when you apply for your visa so they can see when you've entered the UK. They would probably accept your boarding passes but the passport stamps would be much better and I'd definitely go with that.

Oh!  Thanks.    I didn't think of that...

I didn't realize your old passport always got returned to you as well.  I was thinking it was like drivers licenses where they keep and destroy the invalid ones...and that you only got it back if there was already a visa on it or something.  That makes a lot more sense.  Thanks again.

Don't worry about it. It's a lot of information to learn all at once. Once you go through it, you'll be giving people advice too.

Good luck!
