# Citing two authors gets displayed incorrectly

I have a problem with my citations, I want to cite an article with two authors, A Surname and B Lastname. I write it as following in my .bib file:

@article{crillersen,
Author = {Surname, A and Lastname, B},
Title = {Random title},
Year = {2006},
Pages = {1,9 and 14},
Journal ={some journal},
url={http://www.someurl.com/},
}


I get the result:

Surname, A and B Lastname (2006). "Random title". I:some journal, 1, 9 and 14. url:http://www.someurl.com/.

The setup I am using is:

\documentclass{article}

\usepackage[utf8]{inputenc}
\usepackage[swedish]{babel}
\usepackage[backend=biber, style=authoryear]{biblatex}
\usepackage{floatrow}
\usepackage{graphicx}
\usepackage{csquotes}

\begin{document}

\tableofcontents
\listoffigures
\listoftables

\printbibliography

\end{document}


Why do I get the surname first on the first person and the first name first on the second person? I have tried to look though previously asked questions but found nothing about this.

How can I print this correctly?

\DeclareNameAlias{sortname}{family-given}

Previously, I suggested to use last-first instead of family-given, which is equivalent but now deprecated as pointed out below in the comments.
• Note that starting with version 3.3 you should use \DeclareNameAlias{sortname}{family-given} instead. last-first is only supported as legacy alias and should produce a warning. – moewe Sep 21 '16 at 16:50
