Lady Gwen Thompson, English author and educator (d. 1986)

Lady Gwen Thompson (September 16, 1928 – May 22, 1986) was the pseudonym of Phyllis Thompson, author and teacher of traditionalist initiatory witchcraft through her own organisation, the New England Covens of Traditionalist Witches.

Lady Gwen claimed to be a hereditary witch, with connections to the Salem witch trials of 1692, though she could not provide original sources to support these assertions. When she published a supposedly ancient poem called The Rede of the Wiccae, it was believed by some to be partly her own work.
