Ätten Natt och Dags Släktförening:
"The board of the Family Association met yesterday and we discovered a problem with
your line. It concerns Måns Bengtsson and his alleged son Tuve Månsson. The
standard work we are using is authored by Gustaf Elgenstierna and titled “Svenska
adelns ättartavlor”. According to Elgenstierna Måns Bengtsson had four daughters
and just one son named Johan. There is no Tuve mentioned in this very reliable
standard work, so this means we can not confirm your connection to the Natt och
Dag family tree."
