Brandons, Willoughby, etc.

Individuals who have died before the main action of the novel are again parenthesized, while "~~~" indicates an illicit liason. Colonel Brandon's elder brother and the first Eliza Williams were divorced; she was a close relative of the Brandons. Mrs. Smith is Willoughby's cousin.

Note that the amount of money that Col. Brandon has charitably doled out for the upkeep of the younger Eliza Williams is actually probably much less than the amount of money which flowed into the Brandon family upon his elder brother's marriage with the elder Eliza Williams (and which Col. Brandon inherited after his father and brother died).
