At a Jewish funeral can a Non-Jew lead the unveiling of a headstone?

Answer 1

The rituals surrounding death and burial in Judaism are very specific. The funeral must be lead by either a rabbi or someone Jewish (in non-Orthodox communities, it can be either a Jewish man or woman). Although it might be acceptable for a non-Jew to speak at a Jewish funeral in some communities, it would never be appropriate for that person to speak on behalf of the family.

Answer 2

It's permitted but not preferable.
