I have come across a few people whose headstones only display their 'nickname' which may not be their birth name or middle name. For those of us who try to research the people on the headstone and for the benefit of those who may be researching using the only name known by the family (i.e., the nickname), it would be useful to have an optional field in which to place this similar to the maiden name field. I am currently using the (nickname), format in the name field to indicate this but feel that it may be a little misleading as you could not find any documentation - including a death index listing using the nickname or by including the nickname as part of the full name.
For instance on the headstone : Jack Pitt
Actual name: John Richard Pitt
