• Hendrik van Riessen (Q65562488)

The pair ended up on Wikidata:Database_reports/identical_birth_and_death_dates/1

Same for

• Wim Koumans (Q65562451)
• Pieter Kreijger (Q65562452)

See the subject just under here, you could have seen that instantly when opening my talk page.

I see (I probably would have noticed if the page didn't use flow).

Since those dates are either all wrong or just most of them are, I removed date of birth (P569) and date of death (P570) from: Q65562388, Q65562389, Q65562390, Q65562451, Q65562526, Q65562528, Q65562452, Q65562487, Q65562488, Q65562469, Q65562470

Personally, I'd use this approach: https://www.wikidata.org/w/index.php?title=Q65562528&type=revision&diff=1004907988&oldid=980628460

If they all published, it might be fairly easy to get the correct years for these people.
