The Cely Letters are a collection of family correspondence written in the 15th century, which describe the lives and business activities of a family of London wool merchants.
Key members were Richard Cely and his wife Agnes and their sons Robert, Richard, and George.
This collection is one of the few surviving letter collections from the 15th century, along with the Paston Letters and the Stonor Letters.
While the Paston Letters cover a period spanning over 3/4 of a century, the Cely Letters cover a much shorter period of time between 1472 and 1488.
The Cely letters were preserved only because they were used as evidence in a lawsuit.
The Cely Letters are primary sources of information about the English economy and English society at the end of the Wars of the Roses.

The New England Anti-Slavery Society (1831–1837) was formed by William Lloyd Garrison, editor of The Liberator, in 1831. The Liberator was its official publication.

Post-nominal letters, also called post-nominal initials, post-nominal titles, designatory letters or simply post-nominals, are letters placed after a person's name to indicate that the individual holds a position, an academic degree, accreditation, an office, a military decoration, or honour, or is a member of a religious institute or fraternity.
An individual may use several different sets of post-nominal letters, but in some contexts it may be customary to limit the number of sets to one or just a few.
The order in which post-nominals are listed after a name is based on rules of precedence and what is appropriate for a given situation.
Post-nominal letters are one of the main types of name suffix.
In contrast, pre-nominal letters precede the name rather than following it, such as addressing a physician or professor as Dr.
Smith.

The Society of Priests of Saint-Sulpice, also known as the Sulpicians, is a society of apostolic life of Pontifical Right for men, named after the Church of Saint-Sulpice, Paris, where it was founded.
The members of the Society add the nominal letters PSS after their names to indicate membership in the Congregation.
Typically, priests become members of the Society of the Priests of St.
Sulpice only after ordination and some years of pastoral work.
The purpose of the society is mainly the education of priests and to some extent parish work.
As their main role is the education of those preparing to become priests, Sulpicians place great emphasis on the academic and spiritual formation of their own members, who commit themselves to undergoing lifelong development in these areas.
The Society is divided into three provinces, operating in various countries: the Province of France, Canada, and the United States.
