Ancestry.com, a US-based genealogy website has posted a list of Freemason members from the year 1733 to 1923.
"The records demonstrate the extensive involvement which Freemasons have had in British society," Diane Clements, director of the Freemasonry library and museum, said in a statement.
The Freemasons were a fraternal organisation or guild of stonemasons is believed to have formed towards the end of the 14th century. The organisation, which has supposedly had members such as Winston Churchill, has been largely shrouded in mystery about its existence, members, rituals and activities.
The record reveals that Freemason members were commonly engineers, merchants, clerks and farmers.
The judge who oversaw the Titanic wreck and others who evaded punishment were supposedly Freemason members, according to the Ancestry.com list.
Rudyard Kipling, the author of "The Jungle Book", is said to have been registered into the fraternity when he was in Lahore, at its local unit called a lodge.
The modernist writer, Oscar Wilde, famous for his books "The Picture of Dorian Gray" and "The Importance of Being Earnest", who was jailed on charges of being homosexual, is also believed to have been a member since the age of 20, in 1875 from the Apollo University Lodge, Cambridge.
The list states that Winston Churchill, the Prime Minister of Britain during Second World War, was initiated into the Studholme Lodge aged 26 in May 1901.
"We're delighted to be able to offer people an online window into a relatively unknown organisation," Miriam Silverman, senior UK content manager at Ancestry was reported as saying by AFP. "Whilst we can't reveal the inner workings of Freemason ceremonies, what we can tell you is the details of over two million historic members."
