Are the English people friendly to American expats?

DH makes fun of Americans who claim to be 1/8 this or 1/16 that. As if having a great-great grandfather who was born in a foreign country that you've never been to gives you a deep connection with that country.

All of my grandparents were born in Poland. I have no English ancestry at all. I have a much greater connection with England than with Poland because I actually live in England.

To be fair, some Americans manage to maintain their cultural identity including traditions and sometimes language for generations after they are settled in the US.  Your family may not have done this, but mine did, and it took moving here to realise the extent that they managed it.  It wasn't even a conscious thing on their part.  I think they would have a hard time if plopped down in Wales, because they are Americans first and foremost, but they would fit in in ways that others initially have difficulty with.

British people aren't always logical in how they define ethnicity.  Nationality is pretty straight forward, but how they expect you to express your ethnicity largely depends on their political leanings. 

I do know that Brits and Bostonians make terrible beans...

What real baked beans should look like:

You are incorrect. The baked beans you pictured are disgusting, and British baked beans are awesome, especially with pie or as part of breakfast.

Yes, disgusting! Although "real" beans should be made with molasses and no tomato stuff. 

These appear to be poured straight from the tin....

All forms of baked beans are disgusting! There is one debate solved.   

I agree with sonofasailor. Nothing can make the grey, tasteless mess above that the British describe as baked beans palatable. Just yuck! Give me American baked beans any day!

Damn, now I want a tin of Heinz on top of a delicious Scotch pie! Yum yum! 

These appear to be poured straight from the tin....

And they look DELICIOUS!!

I agree!  Ugh, I can't stand the smell of them, one of my flatmates pours them on his fish sticks (fingers if you're English ).

I find that most people I've met here are very friendly towards me.  Many times, people I talk to casually (taxi drivers, cashiers, etc) start telling me about ties they have to the states (family who live there, trips they've taken, etc) when they find out I'm American.  One of the taxi drivers did say that he thinks Americans are better individually, it's when we all get together that he finds us obnoxious, hehe.  Generally, I don't feel like I've been treated any worse or better off for being American though.  I like to think I present myself in a way that is favorable despite where I come from 

Titanic, I hope you don't take this the wrong way, but one thing that does concern me about your posts is your focus on history and tradition. You would not be moving to 16th or 17th century England. You would be moving to 21st century England. England has computer programmers, nuclear physicists and molecular biologists. It's a member of the European Space Agency. My husband, who is a born and bred Yorkshireman, makes his living from the internet.

Modern England has influences from cultures all over the world. The national dish is Chicken Tikka Masala.  It's population, like America's, includes immigrants from all over the world. If you move to England you may find that you have neighbours who were born in Pakistan, Zimbabwe or Albania, not neighbours whose ancestors fought in the War of the Roses. The "traditional English pastime" that I have taken up regularly here is Puerto Rican salsa dancing.

I'm worried that you have an unrealistic view of England and you will be disappointed when you get here.

ETA: Isn't Boston also very well-known for receiving a large number of Irish and Italian immigrants in the past?

Good points- I am a history buff, but I am hip to the fact that England is a VERY diverse place with bits of cultures from all over the planet.  I've been to london and the one American equivilant seemed to be New york- because walking down one street you will see people from all corners of the globe. Yes, Boston recieved a very large number of irish, Italian and Greek immigrants- I'm a decendent of such immigrants. These days we have a large number of Brazllians adding to our diverse culture.

I can see how my postes may seem like i'm a person pining for distant past- I love history, that is my one vice- but i do live in the here and now. Salsa dancing is fun, but i'm terrible at it- I love indian food, but it gives me a case of the thunders....

What real baked beans should look like:

An American size portion would be twice as big and have a side order of onion rings...
This morning i had my daily bucket of coffee...

Damn, now I want a tin of Heinz on top of a delicious Scotch pie! Yum yum! 

The one food i love straight from the tin are sardines. sardines with mustard and Tabasco sauce- VERY tasty

Actually I am a fan of all traditional British Cuisine - Spag Bol, Chicken Tikka, Donner Kebabs, Curry....

Yup!  And others besides.
