Problems with author name

Dear community,

I want to cite an author with two words in his last name. His name is similar to this one:

Hugo Da Vari

with “Da Vari” being his last name. My problem is that Jabref identifies “Da” as a second FIRST name. If I write “da” instead of “Da” it works, because Jabref identifies “da” as a title that belongs to the last name. But “da” is not correct! It should be “Da”.

What can I do?

Thank you so much!

Have you tried to use Da Vari, Hugo and …

Thank you stefan-kolb!!! You have solved my problem!
