Do you give people there full name? for example i have an uncle Willie but is seem weird to call him William on the invite, have the same issue with a few "davy's".....what do you think? We always have called these people Davy and Willie but do you put William, David etc........
Use the full name especially if you are unsure of the shortened or pet name spelling
We used full names as well.
We used the the names we know them by, e.g Davy, Ger, Mick etc. The way we looked at it was, it would see weird to use their full name when we never call them by it
Think I will go with the names as we know them i.e. davy etc, i guess it is a pesonal choice.
