To invite or not to invite

I don't see why you would have to invite them. If someone else brought them to your shower without your permission, then that was on them. I definitely wouldn't add them to the wedding list especially if you know you'd have to invite a whole village of other people connected to her.

You aren't obligated to add them to the list, it's not your fault they decided to show up uninvited. I'm assuming there was a reason you didn't originally invite them in the first place, I personally would stick to that.

You don’t just get to invite yourself places, that’s just rude. It’s nice that she wanted to give you a shower gift, but since she was not invited she should have given it to you at a proper time. I would not invite her to the wedding. Was she just fishing for the wedding invite? And even if you do decide to invite her, why on earth would you have to invite her entire tribe? Just say no to them all.

No. You did not give the shower. You did not invite this person, she invited herself. And all you need say is, when she showed up with no invitation, the hostess graciously allowed her to stay, and participate, not make a scene by asking her to leave. . . . .You need not alter the guest list.
She made the bad mannered mistake of coming uninvited, or accepting someone else's urging to just come, without asking the shower hostess. You owe her no apology, and no wedding invitation if she originally was not getting one.

Omg i just had this same problem!!! My aunt and grandma threw my bridal shower, so they invited ppl from their church and distant family members. My distant said on their way out “see y’all at the wedding!” 🙄 of course my grandma said “of course!”. I’m like noooo we hardly have room for the people invited! Lol so i sent them a nice message on fb and said they can attend the ceremony but i couldn’t promise them a seat at the reception. I feel like people know at this point invitations have been sent out, so obviously they’re not invited, i didn’t invite the other church members who attended. It is a sticky situation

No. They showed up uninvited to your shower, that doesn't obligate you to invite them to the wedding.

I wouldn't invite them to the wedding, since they weren't invited to the shower. It was nice of you to let them stay!

That said, I'd have a plan ready to go in case she, or all four of them, show up to the wedding uninvited, too.

Don't feel obligated to invite her! It's her fault she showed up uninvited

Not at all! Showing up uninvited to any event is just rude and certainly doesn't earn you an invitation to another event.

Not at all. do not feel obligated to invite someone who rudely came uninvited

Agree with PPs, she is in the wrong showing up uninvited - who does that?!. You absolutely should not invite her. I would also talk to whoever invited her to the shower and make it very clear they should not continue to do so.
