Hi,
I'm not sure where the error come from.
It doesn't come from the source, Trismegistos doesn't say that this person
is born in 1999 (1999 is a publication date here, at least in the
interface).
I'm not even sure it comes from Mix'n'match (TM 7726 seems to be WD
Q55088584,
user:Tagishsimon did the match last June[1] and it seems correct).
The problem is probably elsewhere. Probably when the extraction of
Trismegistos was done, the birthdate and the publication date were mixed
up...
The best way is to contact Magnus who runs Mix'n'match and the bot
importing data (or even better, the person who extracted Trismegistos but I
don't know how to find them).
Cheers, ~nicolas
PS: it's not
