German Shepherd dog

I'm looking to learn more about influential working line males, so I did a search for my young female’s heritage and found the following names. Some I immediately recognized and others I haven't heard of.  Where can one find bios (written in English, not German) or other info about what these guys brought to the mix?  Thanks for the help...

My girl:

Males from her pedigree:

Jabina Fjolle

SG Pike von der Schafbachmühle

V Karlo vom Peko Haus

Torro vom Salztalblick

Niko von der Gänsebrücke

V Cliff vom Heidhof

V Fiasko von Gebrüder Grimm

Thanks,
