I'm using natbib for my bilbiography (and I'm working on Overleaf), and I want to have the same format as Harvard style for this, so I use the style agsm, but I want to have the first name then the last name and I want to remove comma between this. So for example:
I have this in my .bib file
@article{label1,
author = {Daniel Aubier and Nicole Silvie and Jean Tetrae}
% ....}
And I have this kind of result actually:
Aubier, D., Silvie, N. and Tetrae, J.
But I want this:
D. Aubier, N. Silvie and J. Tetrae
I know this isn't the real Harvard style, but I want to keep the essential of Harvard style, with this particularity.
Thank for your help!

agsmandmyagsmautomatically perform sorting of the entries, by alphabetical order of the surnames of the authors and editors. – Mico Mar 31 '18 at 23:51.bibI'm wrong when I put author's names. I do it like this actually :author = {Aubier, D. and Blengino, J. M. and Brandt, A. C. and Silvie, N.}– Apodeus Apr 01 '18 at 07:02agsmbibliography style along with thenatbibcitation management package. – Mico Apr 01 '18 at 09:27ff(respll) stands for first (resp last) name and I guessvvandjjwork in case the author's last name is "van Beethoven Jr." – EA304GT Feb 01 '20 at 03:49
