Happy Easter - German Help!

Hello,

I am wanting to send a little note to all my neighbours to say happy Easter. Which is correct:

Wir wunsche Ihren frohe Ostern

or

Wir wunsche sie frohe Ostern

Then is it ok to say Dein at the end?

Kind regards,

Charde

Ich mag, dass Sie ein glückliches Ostern hätten

Sorry my German is REALLY basic. This is what my teacher told me, what is it that you have written?

Ich wünsche Ih n en frohe Ostern (singular)

or

Ich wünsche Ihnen ein frohes Osterfest

Wir wünschen Ihnen frohe Ostern (if you're writing on behalf of yourself and xxxx)

or

Wir wünschen Ihnen ein frohes Osterfest

If you're per "Sie" with the receiver, then you should write "Ihr Chardie"

Second is plural, first is singular?

How should I sign off at the end if it is from my boyfriend and I...

second = plural (you and your boyfriend)

Sign: Ihre Chardie and Joe

Sorry I wrote that after you had written the post.

It is from me and my boyfriend, so can I use this:

Wir wünschen Ihnen frohe Ostern

For formal plural & singular?

O.k. - you and your boyfried are writing to the neighbours. So you can write

Wir wünschen Ihnen frohe Ostern

Ihre Chardie & Joe

Doesn't make any difference if the receiver is one person (Sie = formal) or a whole family.

Danke Schon!!

Sehr gerne geschehen!

Have a happy one
