Azathoth Family Tree

There are at least two original "family trees" produced by members of the "Lovecraft Circle", including the charts made by H.P. Lovecraft and Clark Ashton Smith:

H.P. Lovecraft

"The Family Tree of Azathoth", or "Genealogy of the Elder Races", AKA "Letter 617"
To James F. Morton dated April 27th 1933, SELECTED LETTERS IV, H. P. Lovecraft

This whimsical family tree purports to show the family relationship of Azathoth, Yog-Sothoth, Shub-Niggurath, Tsathoggua, and others to each other, and to Lovecraft and Clark Ashton Smith.

Apparently, Lovecraft wrote the chart in response to a remark from James F. Morton claiming relationship to Jupiter (perhaps in a humorous signature to Morton's letter?): Lovecraft prefaced the chart with the introduction, "Hail, Offspring of Jove! ...Alas - I have only daemons behind me...."

Azathoth Family Tree created by Clark Ashton Smith

Clark Ashton Smith created an alternative family tree (from a letter to R.H. Barlow dated June 16th 1934), mentioning:

• Azathoth (reproduced by fission)
  • Cxaxukluth (androgyne)
    • Tulu
    • Hzioulquoigmnzhah (male)
    • Ghizguth (male) C
      • Tsathoggua D
        • Zvilpogghua
          • Sfatlicllp (daughter who mated with Voormi)
            • Knygathin Zhaum (peopled Commoriom by fission after the human residents had left)
      • Shathak D
• Ycnagnnisssz (fissionary being from the dark star Zoth)
  • Zstulzhemgni (female) C

(The phrasing of Smith's letter seems to suggest that Barlow may have previously supplied a "style sheet" for the family tree with a list of questions about it for Smith, and the resulting family tree was the result of Clark Ashton Smith humoring Barlow.
