'Titles' for a table plan.

I've never been to a wedding where they used titles rather than names for anyone other than the bride and groom.

I'd go with names.

Yup.?

Avoid all the pickles you can - there are plenty to go round!

We aren't having individual places, just allocating surnames to tables. Only one surname per party. So whoever we know 'best' gets their surname on the table plan. If we had set places it would have been first names only.

This is what we did. Including ourselves, Mums and Dads. Only Nannan/Aunties/Uncle had any kind of title associated with them (because we use these prefixes when normally addressing them).

It all gets a bit politically correct with kids and step-kids, double-barrelleds and whatnot, 2 of our families have 3 surnames, others have 2. We've done it so every party has one name. Saved us a stack of hassle. if they were our family we used that surname, or if they had a member of the wedding party in the family we used that surname. We have friends bringing plus-ones and we don't know their surname. In fact a couple of them, we don't even know their first name! I think a friend hasn't decided who she's bringing yet and it's this weekend

Just use their real names
