Fenwicks And Giles

In 1753 Edward Fenwick married Mary Drayton, daughter of Thomas Drayton and by her had many children. After her husband's death, Mrs. Fenwick married William Gerard de Brahm, an engineer officer in the service of the colonies of South Carolina and removed to Philadelphia. Her will is dated 1805. 

"Of the next two Fenwick children, Selina and Matilda, little is known except that Selina was appointed sole executrix of her mother's will and Matilda married Robert Giles." (Source)
