Claims with surname properties are sometimes impossible. For instance, I
tried to add the surname of René Grivart
<https://www.wikidata.org/wiki/Q18330867>, but as I typed "Grivart" in
the property value, the "save" link stays unclickable. Should we
systematically create an item associated with the surname ?
It would be interesting to know how many given names and family names
were not imported from it.wiki's {{bio}} by Amir due to not existing.
In general the notability policy states that you can create an item if
it's required to state something about a notable item, IIRC. As Daniel
noted, however, the usefulness of these properties (and statements) may
be questionable.
