Why not using it for a foaf:Group which includes your Aunt and Uncle ?
So, the mbox will be an IFP for a group consisting of both of them.
It will be OK, since the domain of this property is a foaf:Agent, not
a foaf:Person, unless "ie. an Internet mailbox associated with exactly
one owner, the first owner of this mailbox." means that the owner
should be only a single person ( but in that case the domain should be
changed in the specs).
IMHO, using a group makes sense.

Best,

Alex.
