OK, I had to add a few orders and change the location of the Rieksguard. All that meant I acceded the maximum number of characters on a post so I have re posted, leaving room on each entry for changes to be made easily.
In my search for the perfect knightly order to match my army theme I kept comming across more and more I had never heard of before. I decided to keep track of them and this list was borne. I later found out that there is a similar but smaller list on Warseer (Special thanks to Griefbringer for leading me to more orders). Anyway. I have this list so I thought I would share it. If you know of any other OFFICIAL knightly orders not listed please let me know. Also if you see any mistakes please correct me and give me the source where i can find the correct info myself. Thanks a lot. I hope this list helps you to find that perfect order for you army too. Renowned Knightly Orders TemplarsSigmaritesThe Knights of Sigmar’s Blood
“The Knights of Sigmar's Blood have a long and proud history. Led by their Grand Master Hans Leitdorf, brother of the Elector Count of Averland, their ranks are filled with the men of noble houses across the Empire. Their selection process is considered extreme even among the other Orders, as each Knight in training must spend a year in study within the church where he is judged by the priests as to his worthiness”.http://oz.games-workshop.com/games/warhammer/empire/painting/knights/gallery/default.htm

“The Knights of the Twin-Tailed Orb are followers of Sigmar, named after the two-tailed comet that heralded Sigmar’s appearance among mortals. Like other Sigmarite orders they are renowned for their zeal and fervour. In particular the knights of the Twin-Tailed Orb are famous for their eagerness to prevent the escape of a single tainted foe, and will relentlessly pursue fleeing enemies even when it would make more tactical sense to regroup”.
Warhammer Chronicles, pg 30.Knights of the Hammer
This order was founded just over 200 years ago after the Great War against Chaos. Their chapter house was granted to them by Magnus the Pious. As very pious Sigmarite Templars, they shave their heads before going into battle and wield huge war hammers.
The order took very heavy casualties in the Storm of Chaos. Of the 100 men they sent, 80 died. It may take years for this order to recover their former strength.
Cult of Sigmar article, WD 304The Order of the Hammers of Sigmar
“The Order of the Hammer of Sigmar was founded in Altdorf shortly after the news of the destruction of Mordheim reached the city. Zealous Lectors of Sigmar encouraged the devout sons of local nobles to join the fledgling Order. Once assembled, the Lectors sent the Order into the ruins of Mordheim to restore order and keep the faith (and the faithful) alive throughout the turmoil.
The Templars of this Order can often be found bringing faith to the wavering masses and crushing the skulls of vile heretics. They ride into battle wielding great warhammers of all description, another sign of their devotion to Sigmar.”http://oz.games-workshop.com/games/warhammer/empire/painting/knights/gallery/default.htmOrder of the Jade Griffon
The Order of the Jade Griffon is a templar order presumably devout to Sigmar. Aekold Helbrass, was a former member of the order who turned into a follower of Tzeench. Nothing else is known about this order.
Liber Chaotica: TzeenchOrder of the Red Griffon
This is a small order of Sigmarite templars. They wear a red griffon rampant as their coat of arms. Nothing else is known about this order.
Zavant (Black Library publication by Gordon Rennie)The Knights Griffon
“The Knights Griffon are arguably the most drilled and militaristic Order in the modern Empire. Their daily rituals mostly consist of strict martial training. A veteran Knight Griffon is the epitome of discipline and soldiery on the field of battle. He is able and willing to hold his ground, attack, or retreat in good order should the situation require it.
The Knights Griffon were founded in the year 2305 by Emperor Magnus the Pious as part of his rebuilding of the Empire after the Great War against Chaos. Magnus requested one hundred of the most loyal and devout Knights Panther to join him at his court in Nuln, where he formed an Order of devout Templars directly responsible for the protection of the Temple to Sigmar in the Empire's then-capital. The Knights were deeply honored by this selection and accepted the offer, and the Order of Knights Griffon was incepted. When the crown passed to the Princes of Altdorf in 2429, the Knights Griffon moved their Chapterhouse to the Cathedral of Sigmar in Altdorf to maintain their vow to protect the heart of Sigmar's realm. As a result, there is some animosity between the Knights Griffon and the Reiksguard, each of whom views the other as imposing on their traditional role”. They wear dark green and gold with a yellow or gold rampart griffon insignia. http://oz.games-workshop.com/games/warhammer/empire/painting/knights/gallery/default.htm
WHFB Empire army book 6th edition, pg 39The Hunters of Sigmar
“A relatively new Order, The Hunters of Sigmar have dedicated themselves to hunting down and destroying pockets of Chaos resistance in the Drakwold forest region. The Order was formed by Jerik Wildorn in the aftermath of the Storm of Chaos, mainly in response to the increased presence of Beastmen and other dark and dangerous things lurking in the deep forests of the Empire's northern reaches. Jerik is an expert woodsman and tracker, and these skills are emulated, honed, and perfected by the Order's Knights each and every day. They frequently provide escort services to coaches and merchant caravans traveling through the region. In addition to such duties, the Hunters of Sigmar go out of their way to track and eradicate evil where it lives within the woods. Their strategy revolves around the idea of striking at Chaos before it has time to gather and form a raiding army. By striking in a preemptive manner, lives are saved and small settlements spared the ravages of Chaos.
The average Hunter of Sigmar often spends long periods of time living outdoors. As such, they have to provide their own sustenance and have little time to repair their equipment. They carry everything they might need into the field — you just never know how difficult a trail will be. Mud-spattered and odorous, Hunters are certainly not regarded as the most glamorous Knightly Order. In fact, when they gather together to form a skirmish group, they are often mistaken for a ragtag group of Freelance Knights. However, their relentless struggle against the forces of Chaos is more than welcome in these dark times. It is not uncommon for local people's to offer shelter and food to these brave warriors of the Empire in a gesture of appreciation”.http://oz.games-workshop.com/games/warhammer/empire/painting/knights/gallery/default.htmThe Templars of Sigmar
“Although a Knightly Order, the mysterious group known simply as the Templars of Sigmar are a world away from the warriors in shinning armour of popular image, so much so that they rarely refer to themselves as knights. Instead they battle the foes of Sigmar from the shadows, dealing with subtle and insidious threats such as Chaos cults and reclusive necromancers. In particular they excel at battleing users of sorcery, as magic and trickery are tools often used by the servents of darkness. All that most common folk see of the Templars of Sigmar are the elaborate trials and fiery executions used to cleanse the souls of the wicked, and because of this they are most often known simply as Witch Hunters”.
They often wear black clothes, large rimmed hates and black or brown capes. They favor the use of the pistal and sword but carey many types of weapons. The sympol of the order is a silver hammer of sigmar, often worn as a neckless.

Witchhunter's HandbookKnights of the Fiery Heart
The Knights of the Fiery Heart is one of a number of martial orders in the service of the temple of Sigmar. They are an elite cavalry unit of Sigmar templars, dedicated to the destruction of all goblinoids. Together with the Order of the Fist (a secret sister order) they make up the Order of the Holy Knights of Sigmar. They are the personal guard of the Grand Theogonist. Aldred "Fellblade" Keppler, a member of this order was a one time companion of Felix and Gotrek.
The Fiery Hearts have a long and glorious history, dating from the civil wars when the cult of Sigmar was outlawed in Talabecland. They wear white surcoats and barding and carry white shields. They use red hearts as insignia on their shields with black maltese crosses mixed in.

This is an “ancient temple order of Knights famous for their part in the defeat of Mannfred von Carstien at the Battle of Hel Fenn”. In that battle, the knights were led by the Grand Theogonist, Kurt III. References to the order coming to Hel Fen “all the way from Altdorf” suggest the order is located there although it might only be referring to the Grand Theologist. The Wight Lord, Gothard, known as the Undying Knight, was once a member of the Knights of the Divine Sword.
