Metal With Violin/Fiddle

I think Iced Earth uses violins or something, they pull it off greatly.
 
I remember Believer did the 'Trilogy of Knowledge' on their last album 'Dimensions'.

Also the song 'I Remember' by Kataklysm.
 
Also try -

virgin Black
Haggard
Asunder

I think they use cellos but yah, more or less a similar sound.(although 'cellos' sound a bit more deeper, which suits doom/gothic metal)
