The Lyndon Sisters

 * Abduction Is Love: After Victoria tells him to go away, Robert kidnaps her and takes her to a cottage in the middle of nowhere.
 * Fiery Redhead: Eleanor.
 * Frame-Up: A rather more gentle example than usual - someone is framing Eleanor so that she looks incompetent, as opposed to guilty.
 * Heroes Want Redheads: Charles to Eleanor.
 * The Jailbait Wait: really, really wanted Charles to do this.
 * Parental Marriage Veto: Robert and Victoria.
 * Reformed but Rejected:
 * Wacky Marriage Proposal: Charles to Eleanor - he needs to be married to inherit money, she needs to get out of her house.

Agents of the Crown

 * Arranged Marriage: Percy and Caroline.
 * Mistaken for Spies: Caroline.
 * Rebellious Princess: Caroline.

The Bridgertons

 * Altar the Speed: Simon and Daphne, Anthony and Kate, and Philip and Eloise all end up having to get married swiftly due to being discovered in compromising situations.
 * Dark Secret:
 * Parental Marriage Veto: Sophie is very worried about this, although it never actually materialises.
 * Secret-Chaser: Eloise's determination to find out who Lady Whistledown is.
 * Secret Diary: Colin has one, which Penelope finds.
 * Secret Identity:
 * Secret Relationship: Sophie and Benedict, for very good reasons - she's illegitimate and his mistress.
 * Speak Now or Forever Hold Your Peace:
 * Theme Naming: The Bridgerton siblings are named A-H in order of age.
 * What an Idiot!: Eloise, who, despite having grown up in Regency England, thinks it's a good idea to go unaccompanied to the house of an unmarried man for a long stay.
 * She was under the impression that his maiden aunt would be around to chaperone them, though.
 * To be fair to Eloise, she was really distraught over her feelings at the time, being a 28-year-old spinster when her best friend (ALSO a 28-year-old spinster) had just gotten married. People (modern and historical AND fictional) have made stupid mistakes over less.

The Two Dukes of Wyndham

 * Sympathetic POV: The duology is told from two main perspectives: that of the long-lost Duke of Wyndham, and that of the current Duke of Wyndham (who is understandably unhappy at the prospect of losing his inheritance).

The Bevelstoke Series

 * Convenient Miscarriage:
 * Secretly Wealthy:
 * Brainless Beauty: Averted. Olivia may be exceptionally pretty, but she is by no means stupid. In fact, she's rather pragmatic and would much prefer a newspaper to a novel.
 * Mustache De Plume: Inverted.
