Sending a formal invitation letter to someone to attend a conference... how should I write the person's middle names? Example:
Dr. Francis,Jean,Auguste Richard or Dr. Francis J.A Richard or what?
I would not consider it usual to include the middle names at all: Dr Francis Richard should be enough. If the man always uses his middle names for some reason (or there is another person with exactly the same name, causing confusion) I would use Fr. Francis J. A. Richard.
