FYI: I have imported all father (P22), mother (P25), child (P40) and spouse (P26) between extant items from CBDB. This does not include people not having an item yet. Some wives without a name may have useful information (father, mother, etc), which meets point 3 of Wikidata:Notability and may be useful to build a family tree, so I plan to create items for them (No sooner than July).
By the way I found hundreds of duplicated items the bot created. Some are duplicates within CBDB. Are there any way to report them? also for reporting errors in the database (an obvious example: the father of Chongzhen Emperor (Q10069) is wrong)?
