TO @cindalu: valid Question…
As pointed out the Announcement would of course be in your Married Name, and if the most formal kind (ie look like a Wedding Invite) then it would have your full name normally (ie Cindy Luanne) which might give the receiver a bit of a clue.
Many would also include a photo, either a Wedding Photo if they are sent a bit after the Wedding itself, or there could be an Engagement Photo of the happy couple enclosed. People do like receiving photos when there is big life event being celebrated (think Baby Announcements)
OR if none of these work… the Announcement is also often seen as a chance to update people on not only your new marital status but also your change of address…
It would be perfectly acceptable to insert a small printed card, with your new address, upon which in pen you’ve hand written…
Dear Aunt Martha,
Please note my change of address
OR if you are moving with your new Husband to another city maybe elaborate on the note and say
Dear Aunt Martha,
Please note my change of address, I’ve moved from Atlanta to Aberdeen as that is where Paul is originally from
Anyhow, times have changed a bit on the Wedding Announcement front from the days when they were very formal cards that looked very much like a Wedding Invite mailed out the day of the Wedding and went to relatives who altho you might not see often corresponded with on a regular basis (or your Momma did). The majority of Brides choose not to use Wedding Announcements at all.
Personally tho, I still like them, as I think they are a nice touch for just the circumstance you mentioned… relatives you may have that you don’t see often… or when someone chooses to Elope.
In my own case, we went a less formal route, and combined our Thank You Cards and Wedding Announcements into one… we had Photo Thank You Cards printed, that just said We Eloped, and lots of space to write. When it was to serve as a Thank You for a gift we wrote a note, when it was to announce that we married, we let it stand as is, or wrote a different note. We also got pretty address labels that we put on the envelopes so everyone was up to date on that info as well.
Hope this helps,
