I have sent my wedding invites out and a lot of them say, for example, "To Donna and family"
Is this really rude that I didn't name individuals? For example, her DD is only 8 so would naturally come under family, but how about her DP who I don't know etc? He's more than welcome to come, I just don't really know him.
Another reason for me not putting names of everyone is that I don't have everyone's address and know if I invite say, a big aunt, and include "and family" or other invitations within saying "Joseph and family" if they have a family of their own, they will get this etc.
For example, with my great aunts invite, I sent my cousins invite and put 'and family'. But DCousin'a children have their own families and she wondered if they were invited too? They are of course.
I've been really shit at this, haven't I? 
Have I caused offence?
