Genealogy Research Methods and Strategies
Effective genealogy research goes beyond searching databases. Understanding research methodology, evidence analysis, and the Genealogical Proof Standard produces more reliable and defensible conclusions.
The Genealogical Proof Standard
The Genealogical Proof Standard (GPS) is the professional standard for evaluating genealogical conclusions. To meet the GPS, a researcher must conduct a reasonably exhaustive search, provide accurate and complete source citations, analyze and correlate the collected evidence, resolve any conflicting evidence, and write a soundly reasoned conclusion.
Meeting the GPS does not require perfection, but it does require intellectual honesty about the strength and limitations of the available evidence. A conclusion based on a single document that conflicts with other evidence is not proven — it is a hypothesis that requires further investigation. Experienced researchers are comfortable saying "I don't know" rather than accepting an unverified family tradition as genealogical fact.
The GPS distinguishes between three types of information: primary information (provided by someone with direct knowledge of the event at the time it occurred), secondary information (provided later or by someone without direct knowledge), and undetermined information (when the informant's knowledge cannot be assessed). Combining multiple independent sources of primary information provides the strongest possible basis for a genealogical conclusion.
Cluster Research: The FAN Club Method
One of the most powerful research strategies is cluster research, sometimes called the FAN Club method (Family, Associates, and Neighbors). This approach recognizes that our ancestors did not live in isolation — they moved with friends and relatives, settled in communities with people they knew, and repeatedly appeared in the same records alongside the same individuals.
When you reach a brick wall in your direct-line research, shift your focus to the people surrounding your ancestor. Research all of their siblings, neighbors listed in the same census enumeration district, witnesses on legal documents, and members of the same church congregation. Often, a cousin or neighbor who migrated earlier has left records that reveal the family's origin in another state or country.
The cluster method is especially effective for researching ancestors in early periods when records are sparse. In colonial New England, for example, extended family groups typically settled together, and deconstructing the cluster of associated families often reveals relationships that are not stated explicitly in any document.
Breaking Through Brick Walls
Vary Your Search Terms
Spelling was not standardized before the twentieth century. An ancestor named Schreiber might appear as Shriver, Schriber, Schrijver, or dozens of other variants. Use wildcard searches and phonetic search tools like Soundex to cast a wider net.
Look at Overlooked Record Types
Researchers often focus on the major databases and overlook specialized collections: tax records, school enrollment lists, church membership rolls, county history books, fraternal organization membership files, and local newspaper archives often fill gaps in the major platforms.
Use DNA Evidence
When documentary research hits a dead end, DNA matching can break through. Shared DNA segments with multiple cousins can point toward specific ancestral lines and suggest surnames or geographic areas to investigate further.
Working with Difficult Record Sets
African American genealogy presents unique challenges before 1870, when enslaved people did not appear by name in most federal records. Research strategies include examining the records of enslavers identified through post-Civil War Freedmen's Bureau records, plantation records, and estate inventories; researching in the Freedmen's Bureau records (1865–1872), which contain labor contracts, marriage records, and ration records; and using DNA testing to connect with biological relatives who may have more documentary information about shared ancestry.
Native American genealogy often requires consulting specialized records held by the Bureau of Indian Affairs, tribal enrollment records (including the Dawes Rolls for the Five Civilized Tribes), and records held by specific tribal nations. Understanding the particular history and record-keeping practices of the nation you are researching is essential before beginning.
For recent immigrant families, foreign records research becomes necessary once you have exhausted American sources. Civil registration records, church registers, and military records from the country of origin may be held by national archives, regional repositories, or local churches. Many are now available online through FamilySearch, Ancestry, or specialized genealogy platforms for specific countries and regions.
