Genealogy: Frequently Asked Questions

Genealogy research touches everything from birth certificates and census rolls to DNA matches and ship manifests — and every step raises questions that deserve precise, honest answers. This page addresses the most common questions encountered when tracing family history, covering where to find records, how professional standards work, what jurisdictional differences affect access, and what to expect before starting a serious research project.

Where can authoritative references be found?

The three most-cited institutional sources in American genealogical research are the National Archives and Records Administration, the Family History Library operated by The Church of Jesus Christ of Latter-day Saints in Salt Lake City, and state-level archives maintained by each of the 50 states. NARA holds federal records including census schedules, military pension files, naturalization records, and passport applications. The Family History Library — accessible digitally through FamilySearch — holds microfilmed records from more than 100 countries. For county-level records like deeds, probate files, and vital registrations, state archives are the first stop, though county courthouses often retain originals. Major subscription platforms including Ancestry.com aggregate digitized collections from these institutional sources, but the originals remain in public hands.

How do requirements vary by jurisdiction or context?

Access to vital records — birth, marriage, and death certificates — is governed entirely at the state level, and the variation is substantial. As of 2024, the number of years before a birth certificate becomes publicly accessible ranges from 25 years in some states to 100 years in others. California, for example, restricts certified copies of birth records to direct family members regardless of record age, while states like Ohio have opened original birth records to adult adoptees through legislation passed between 2014 and 2023. For immigration and naturalization records, federal privacy rules under 5 U.S.C. § 552a limit access to records for living individuals. Military records destroyed in the 1973 National Personnel Records Center fire — estimated by NARA to represent 80 percent of Army discharge records from 1912–1959 — require alternative reconstruction strategies.

What triggers a formal review or action?

In genealogical work, a "formal review" typically means scrutiny under the Genealogical Proof Standard (GPS), the framework published by the Board for Certification of Genealogists. The GPS is activated when a conclusion might be contested — in lineage society applications, legal proceedings involving inheritance or citizenship, or published genealogies. The standard requires a reasonably exhaustive search, complete citations, analysis of each source, resolution of conflicting evidence, and a soundly reasoned written conclusion. Lineage societies like the Daughters of the American Revolution require documented proof chains back to a qualifying ancestor, with every generational link supported by primary documentation. Hereditary lineage societies each maintain their own evidence standards, which vary in strictness.

How do qualified professionals approach this?

Credentialed genealogists hold either the Certified Genealogist (CG) designation from the Board for Certification of Genealogists or the Accredited Genealogist (AG) credential from the International Commission for the Accreditation of Professional Genealogists. Both require demonstrated competency examinations and ongoing education. A professional begins with a defined research question, constructs a research plan, then works from known to unknown — documenting each primary and secondary source consulted. When conflicting evidence appears, the resolution process is systematic: resolving genealogical conflicts involves weighing source origin, information type, and evidence quality against each other. For hiring a professional genealogist, the Association of Professional Genealogists and the National Genealogical Society both maintain directories of practitioners.

What should someone know before engaging?

Three things matter before opening the first database. First, what is the actual research question? "Find my family history" produces unfocused work; "Identify the parents of Johann Müller born approximately 1842 in Bavaria" produces actionable research. Second, what records already exist in family hands — old documents, photographs with names on the back, letters with return addresses? These are free primary sources. Third, understand that brick walls — research dead-ends — are the norm, not the exception, particularly before 1850 when US census records named only the head of household. Researchers new to the field can orient themselves at the genealogy research overview, which maps the full landscape of record types and methodologies covered across this reference.

What does this actually cover?

Genealogy as a discipline spans documentary research, genetic analysis, and historical context. Documentary research includes vital records, US census records, military records, land and property records, probate and will records, church records, newspaper archives, and city directories. Genetic genealogy — primarily autosomal DNA, Y-DNA, and mitochondrial DNA — adds a biological dimension that documentary records cannot replicate. Specialized research tracks address distinct populations, including African American genealogy, which requires navigating slave schedules and Freedmen's Bureau records, and Native American genealogy, which involves federal tribal rolls and Bureau of Indian Affairs records.

What are the most common issues encountered?

The 4 most frequently encountered problems in genealogical research are: (1) identical names across multiple individuals in the same county — solved through cluster research; (2) missing or destroyed records, particularly courthouse fires that affected courthouses in 30+ Southern counties during and after the Civil War; (3) surname spelling variation before standardization, especially in immigration records; and (4) incorrect family lore accepted as fact without documentation. The cluster research method — researching neighbors, witnesses, and associates alongside the target individual — resolves a significant proportion of brick walls caused by the first two problems. DNA testing for genealogy increasingly resolves cases of unknown or misattributed parentage where documents have failed entirely.

How does classification work in practice?

Genealogical sources are classified along 3 axes: source origin (original vs. derivative), information type (primary vs. secondary), and evidence quality (direct, indirect, or negative). An original source is the first recording of information — a county death register entry made at the time of death. A derivative is something made from an original — a transcribed index, a digitized image, a published abstract. Primary information comes from someone with firsthand knowledge of the event; secondary information comes from someone who did not witness it. These distinctions matter because a single document can contain all combinations: a death certificate is an original source containing primary information about the death date and secondary information about the deceased's birthplace (reported by a grieving spouse who may not have known exactly). Citing genealogical sources correctly requires recording all three classification layers so any reader can evaluate the chain of evidence independently.
