You seem to have this posted which is just easily proven wrong
Firstly the "supremes" group is a masonic usa based group from a schism in 95( not at all ancient ...1995) and they are the children of the ancient european based sovereign group(1100's).


"The Sovereign Military Order of the Temple of Jerusalem (SMOTJ), is the United States affiliated Grand Priory of the Ordo Supremus Militaris Templi Hierosolymitani (OSMTH), "


here is a little eye opener for the readers.

notice that the osmth could not register their own name at the United Nations...look for the word supreme in their title v the word soveriegn in the UN title.

quite laughable really the usa freemasons mistakenly translated the Orders name and registered themselves as the wrong name(LMAO) when they had the masonic schism in 95 they mistook the name as supreme instead of what it should have been (sovereign).
They are large membership but they are not any form of ancient templars.

Here some more information poving this site has no idea

Notification of Current Legal Position following a recent court case.
Scottish Knight Templars Sovereign Military Order Temple Jerusalem(R)TM. SKT-SMOTJ(c)
The above Patented Trade mark was applied for under the Trademarks Act 1974.
The application was to register and protect the usage of our Orders continuing name, Scottish Knight Templars Sovereign Military Order Temple Jerusalem®TM. The Patent Registration was granted by the Intellectual Property Office on the 17th of August 2007.
On 21st of September 2007 Mr Paul McGowan lodged an Invalidity Claim against the registered Trademark. He claiming and citing he was acting on behalf of several Websites. These are as follows:
A/ Our own Website of SKT-SMOTJ.
B/ Mr McGowans; Grand Priory of the Knights Templar in Scotland.
C/ He also cited the Ordo Supremus Templi Hiersolymitani OSMTH INC USA under Admiral Carey, he using its EEC Registered Patent name as his evidence. Mr McGowan was proven to the Court to be falsely claiming that the OSMTH USA is a Sovereign Military Order, and recognised as such by the UN. He also claimed that Supremus in Latin means Sovereign. No, it does not, and evidence submitted by us proved otherwise beyond any doubt. The evidence submitted confirmed their registration is in their USA corporate name, and uses Inc at end; its Sovereign name is not legally applicable outwith USA. They have no links to this Order since they left it in 1964 to join Fontes OSMTH. The OSMTH Schism in 1995 as they were the Majority who left Fontes, they are now the only current legal OSMTH and hold Swiss and EEC Patents to prove this.
D/ Commandery of Jacque De Molay 1314 OSMTH. We proved no links to this Order.
E/ The Gnostic Templars website. No links
F/ Poor Knights of Christ Temple of Solomon in Scotland under Mr Vince Zubras USA. No Links.
G/ Militi Temple Scotia. Proven to Court they have No links to this continuing Order, or its history.
H/ Former OSMTH (Regency) Orders under Mr Fontes. Submitted Evidence of Schism in 1995, and Papers ref September 18th in Porto 2008 proved that there is legally now no OSMTH Regency.
These named website’s along with numerous other written evidence in the form of Documentation, formed Mr McGowan’s opposition of Invalidity. He also citing numerous breaches, passing off, in areas of the Trade Marks Act 1974 also submitted by Mr McGowan.
The Case was submitted to the Court Examiner for his Final decision.
The conclusion of the Case 16/7/2009 found in favour of James McGrath on all legal matters, and other counts.
All the grounds and submitted evidence for Invalidity etc, made by Mr McGowan failed in its total entirety.
The Rights of the Patent Trade mark continue now in its Registered Format.
Mr McGowan was given twenty eight days leave to Appeal the Courts decision to the Court of Session in Scotland. The Deadline was 13/8/2009, No appeal was lodged.
The Court Decision of 16/7/2009 was implemented by the High Court. He was also ordered by the Court to pay a lump sum of £900 to Mr McGrath within Seven Days by 20/8/2009. Despite McGowan knowing this since July 2009 No payment has been received.
This is a breach of compliance of a Court Order; it will be legally pursued by us.

Criminal Act. Any other Organisations, or Website/s cited by Mr McGowan in this case must with immediate effect cease and desist from using our Registered Trademarks, or its format, false claims of any connection to us, our History etc. It is a serious criminal offence, and any further breaches will lead to prosecution.
THE SKT-SMOTJ(c). IFA-OCMTH(R)TM

I suppose you have to expect this blatant kind of error ...ie calling OSMTH masonic SUPREMES group a form of Templar...

This is what happens when a site uses wikipedia as its primary reference!!!
Next they will be using GAOTU. LOL
ROTFLMAO
