Tetragrammaton Stained Glass

Photo of this Tetragrammaton inside a Star of David stained glass is courtesy of evissa who published it on Flickr under the title Dedicated to King Edward VII (9 November 1841 – 6 May 1910). It was shot at St Ann's Church, Manchester, England.
Tetragrammaton is the Hebrew name of the Lord and it is composed of 4 letters.

I asked my friend Athol Bloomer

Do you know what is the Hebrew Tetragrammaton inside a
Star of David doing on this stained glass in St Ann's
Church, Manchester, England?

He answered:

Yes both Queen Victoria and her son Edward VII are said to have been supporters of British Israelism. It is also said that Prince Albert (father of Edward VII) was really the son of a Jew Baron Moysen who was the lover of his mother.
