How do I correct people using the wrong name?

[Szyz2020]

I changed my name by deed poll 3 years ago a couple of years after marrying my second DH. I had kept DH1’s name as it was the same as my DC, when they were old enough for it not to matter I changed to DH2’s name.

Twice in one week I have been referred to by my previous surname, once by someone who I know through DH1 and once by someone who doesn’t know DH1 at all but knows me through DH2.

I find it really annoying and irrationally upsetting. My email reflects my new name and someone has emailed me using my old name - but they are a nice person and they’ve sent me an invitation so it feels bad tempered and bad mannered to reply with a correction.

What would be a nice way to correct people when they do this without sounding like I’ve got a stick up my arse?!

My mum had this too - she went back to her "maiden" name when she divorced from my father but one friend kept writing Christmas cards addressed to her with my father's surname.

Eventually (after about 15 years!) my mum rang her up and put her straight.

I have to confess though that when my cousin got married his wife double-barrelled her name with his but I am too lazy to write

Mr Williamson and Mrs Peterson-Williamson on the envelope.

I think this year I might just write John and Jane and the address....

*not their real names
