Read it through once

Mrs. Henry van der Luyden had been Louisa Dagonet, and her mother had been the granddaughter of Colonel du Lac, of an old Channel Island family, who had fought under Cornwallis and had settled in Maryland, after the war, with his bride, Lady Angelica Trevenna, fifth daughter of the Earl of St. Austrey. The tie between the Dagonets, the du Lacs of Maryland, and their aristocratic Cornish kinsfolk, the Trevennas, had always remained close and cordial. Mr. and Mrs. van der Luyden had more than once paid long visits to the present head of the house of Trevenna, the Duke of St. Austrey, at his country-seat in Cornwall and at St. Austrey in Gloucestershire; and his Grace had frequently announced his intention of some day returning their visit (without the Duchess, who feared the Atlantic).
