The Administrative series contains reports, correspondence, a small number of financial records, and several copies of the state and national organizations' constitutions and by-laws. Along with reports from the president, the treasurer, and the Junior Membership Committee, the series includes reports from the state society's two chapters.

The Membership series comprises the bulk of the collection, and primarily contains membership applications. These applications include background information on the member, including age, occupation, immediate family members, religious affiliation, educational history, and other organizations to which the member belongs, as well as genealogical information connecting the member to a verified Huguenot line and references verifying that information. The series also includes handwritten indexes to the application, which cross-reference the surname of the member and the surname of the ancestor with the membership number.

Most of the members are college-educated, and most of the male members are professionals and white-collar workers. Initially, most of the female members listed themselves as housewives, and many appeared to have college degrees. More recently, female members listing professions and careers have increased.

Members range broadly in age and geographic distribution. While the large majority of members reside in Pennsylvania, there are members from all over the United States. Members from other states seem to be interested in the Pennsylvania society because their first ancestors in the United States settled in this state. Pennsylvania was one of the earliest enclaves of Huguenot immigrants in the United States, so it is likely that many Huguenot descendants in the country have some connection to it. In addition, many of the applications are transfer applications from other state member societies, indicating that many members chose to affiliate with the Society of the state in which they resided, and transferred their membership when they moved.

The applications often provide the Protestant denomination and church with which the member is affiliated. Most of the denominations are represented, including Presbyterian, Protestant-Episcopal, Evangelical and Reformed (now part of the United Church of Christ), Methodist, Lutheran, Evangelical Lutheran, Episcopal, Baptist, Methodist-Episcopal, Anglican, Unitarian, Congregational, Quaker, Moravian, Christian Scientist, and Seventh Day Adventist.

The bulk of the applications in the collection represents people who have been accepted as members of the Society. There are a handful of applications that have not been given membership numbers, and may have been rejected. However, there is only one application in the collection that expressly states that it has been rejected by the Society. This applicant was rejected on the grounds of religious affiliation. Although born into the Protestant faith, the applicant converted to Judaism when she married a Jewish man.

The Membership series also includes junior membership applications (arranged alphabetically by last name of member), printed membership lists, and membership cards. The cards are divided into three runs: old membership cards, membership cards, and deceased member cards. The old membership cards record name, address, dues paid, and date of the receipt of dues. These cards appear to date from 1918 to the mid-1950s, but in most cases each individual card covers a ten- to fifteen-year period of dues payment. The membership and deceased member cards include the membership number, name of member, name of spouse, address, ancestor's name, and date elected to membership. These cards primarily span the second half of the 20th century. They were probably created and maintained by the Society's registrar, and therefore, the information included on the card varies slightly as registrars change. The election dates of members on the deceased member cards span from the Society's founding in 1918 to the mid-1970s.

The Genealogical Research series documents the Society's stewardship of recognized Huguenot ancestral lines, and demonstrates its continuing dedication to the exploration of lines that have not yet been established. The series includes six different card indexes: Ancestor/Descendant files, Genealogy cards, the Refugee French Clergymen index, the Walloon (French-speaking people of Celtic descent living in the southern parts of Belgium) index, Swiss family names, and Dutch family names. The files probably all served to verify the connection of members to established Huguenot lines. The registrar of the Society probably maintained the cards, and Helen Noble Worst, the registrar in the early 1950s, was involved in doing at least some of the research.

The series also contains a draft copy of "Huguenot Families" compiled by Mrs. D. Dorsey Wolf, Registrar, for the Proceedings of The Huguenot Society of Pennsylvania. The item is not dated, but Mrs. Wolf served in her capacity as registrar from the mid-1950s to 1970. The material is organized by family name, providing a page or two of genealogical information on that line of Huguenot ancestry.

The Printed Material series consists primarily of programs and invitations for events sponsored and organized by The Huguenot Society of Pennsylvania. These include celebratory events commemorating the Edict of Nantes, the Protestant Reformation, and the Heidelberg Catechism. There are also programs for church services sponsored by the Society, as well as invitations and programs for annual congresses and meetings. This series also includes the first three issues of the Huguenot Society of Pennsylvania's newsletter, thirteen issues of The Cross of Languedoc (the newsletter of the National Huguenot Society), yearbooks and directories of other state member societies, and newspaper and magazine articles. Many of the magazine articles are from South African magazines and discuss the Huguenot communities in that country.

The Artifacts series contains two woodblocks, five metal printing plates, and two copies of the Huguenot cross embossed on paper. The woodblocks and metal printing plates have images of the Huguenot cross, the Society's seal, and the Society's name.
