Thanks a lot, looks nice!
I think you missed a few there: https://www.wikidata.org/wiki/Property:P1015 https://www.wikidata.org/wiki/Property:P1005 https://www.wikidata.org/wiki/Property:P949 https://www.wikidata.org/wiki/Property:P1207
Q42 is a treasure trove for these :) Will see if there is more.
