While Eva is a dutch first name, Stratt isn't a Dutch last name.
I hereby present reasons for Eva Stratt to be named that
1. Andy Weir did his research bad (boooring)
2. Stratt has a German dad and a Dutch mom but lives in the Netherlands (plausible)
3. Grace misheard Stratt say 'I'm Deutsch' and assumed she was Dutch (funny as hell and very in character)
Option 3.5
Grace missheard, WAS eventually corrected, got hit with that sweet sweet amnesia juice and never recovered the memory of being corrected, therefore by her own fault returning Eva to the incorrect status of Dutch in Grace's head for the rest of their natural lives as some form of ironic cosmic karma.
