Notes:
[1] The text indicates that Shima’onari and Likimeya may be siblings in addition to being husband and wife. This may be an error in the appendix.

[2] Jiriki describes Kira’athu as his cousin on page 682 of To Green Angel Tower, part one, but her parentage is not clear.

[3] Jiriki refers to An’nai as his kinsman, but An’nai’s relationship to House Sa’onserei remains unclear.
