First of all, the name is extremely common in Sweden...
I think she did some vocal duties for Oxiplegatz featuring Alf Svensson from At The Gates way back in the 90ies, but I'm not sure. Maybe that can help your googling atleast.
Actually, Sara Svensson is like John Doe, or finnish Matti Meikäläinen - meaning: there was no female called Sara S. recording those vocals - ´twas mister Stanne.
