"For dating FW notes, there's an extremely important sequence in the early notebooks, as the generic human roles begin to take on personal identities. (Hayman was the first to point this out, in "Wake in Transit".) The following abbreviations appear even in the Ulysses notes, and persist in the earliest FW notes: M(an), W(oman), H(usband), W(ife), OGG (Old Gummy Granny), RL (Rich Lady?), OM (Old Man) In the spring of 1923, characters from Wagner's Tristan suddenly predominate: Trist, T, I, Is, Brang(aene), M(ark) ...along with P for Patrick and K for Kevin. Mark's identity is extended to make him Isolde's father, and his name changes to 'Pop'. His wife appears briefly as Mop. By autumn 1923, Pop has become Earwicker or HCE or E, and his wife ALP soon after. Tristan and Isolde are usually T+I, and the idea that they're mirror images probably led to the adoption of an inverted-T siglum for Issy." [cite]
