addressing thank you cards to same sex couple, what's the correct way?

[LydiaWickham]

So, obviously it's Mr. [one surname] and Mr. [other name] on the card, but which one first? The person you know better (in this case, a family member and so probably the person who actually went to get the gifts for our family) or should you put them alphabetically?

Really? Does it matter? I'd probably put the person I know best, but I doubt it makes much difference or that they'd notice either way.

I think either way would be fine :)

Just put jim jones and john smith, or whatever their names are. Simples.
