Understanding the Basics of Family Tree Research
Family tree research is the process of documenting your relatives and creating a visual or written record of how family members connect across generations. This includes gathering information about birth dates, marriage dates, death dates, locations, and relationships between people in your family line.

Starting a family tree begins with what you already know. Write down the names, birth years, and locations of your parents, grandparents, and any other relatives you can recall. According to genealogy researchers, about 20 million Americans have created family trees online in the past decade, making this one of the most common family history projects.
The basic structure of a family tree shows direct ancestors (people you descend from) and their siblings (your aunts and uncles). Most people start by researching upward, going back to their parents' and grandparents' generations. Some people also research sideways, looking at cousins and extended family members.
Understanding the terminology helps. Your direct line includes your parents, grandparents, great-grandparents, and so on. Collateral lines include siblings, aunts, uncles, and cousins. Knowing these terms makes it easier to organize information and communicate with other researchers about your family.
Practical takeaway: Begin by creating a written or digital list of family members you know personally, starting with your parents and going back as far as you can remember. Include names spelled as you know them, approximate birth years, and locations where they lived. This foundation makes all future research more organized and focused.
Gathering Information From Family Sources
The most valuable information often comes from your own family. Relatives who lived through earlier time periods can share details that no public record contains. Before looking at documents, talk with older family members about what they remember about their parents, grandparents, and earlier generations.

Family documents provide concrete evidence for your research. These include birth certificates, marriage licenses, divorce papers, death certificates, and obituaries. Photos sometimes contain dates or locations written on the back. Family Bibles often have handwritten records of births, marriages, and deaths spanning multiple generations. One genealogist discovered that her grandmother's Bible contained names and dates going back five generations—information that would have taken months to find in public records.
Letters, journals, and diaries offer personal details and context about how your ancestors lived. Immigration papers, naturalization documents, and citizenship records show when and why relatives came to the United States or other countries. Military service records may be available for relatives who served in wars or peacetime military roles.
Consider creating a questionnaire for relatives. Ask about family stories, maiden names, locations where people lived, occupations, religious affiliations, and any family photos or documents they have. Younger relatives may not know the answers, but older relatives can often provide surprising details.
Practical takeaway: Conduct structured interviews with relatives, recording their responses with permission. Ask specifically about names, dates, locations, occupations, and any family stories about why relatives moved or interesting events they remember. Keep organized notes of what you learn and which relatives provided the information.
Navigating Public Records and Documents
Public records are documents created and maintained by government agencies, schools, courts, churches, and other institutions. These records form the backbone of genealogical research because they contain official information about when and where people were born, married, died, lived, worked, and owned property.

Birth and death certificates are primary sources—documents created at or near the time of the event. In the United States, most states began requiring birth certificates in the early 1900s, though some states started earlier. Death certificates typically contain the person's age, birthplace, parents' names, spouse's name, and cause of death. Census records, taken every ten years in the United States, list household members' names, ages, birthplaces, occupations, and relationships. The 1940 Census, for example, included information on about 132 million people and is freely searchable online.
Marriage records show who married, when, and often where. Divorce records document when marriages ended. Land records indicate property ownership and transfers, which can help establish where someone lived during a specific time period. Court records may include probate documents, which show how a person's property was distributed after death and often name family members who inherited.
Church records are particularly valuable because they documented baptisms, marriages, and burials sometimes before government agencies did. Newspapers contain birth announcements, marriage notices, obituaries, and sometimes articles about significant family events. Naturalization records show when immigrants became U.S. citizens.
Practical takeaway: Create a research log for each ancestor, listing what records you've checked and what you found. Include where the record came from, the date you accessed it, and any information it contained. This prevents duplicate work and helps you identify gaps in your research.
Using Online Genealogy Resources and Databases
Numerous websites offer digitized records and tools for family tree research. Understanding what each resource contains helps you search more effectively. Many sites offer both free and subscription-based access to different record collections.

Ancestry.com, the largest commercial genealogy platform, provides access to millions of records including Census data, military records, immigration documents, and digitized newspapers. FamilySearch.org, operated by The Church of Jesus Christ of Latter-day Saints, offers free access to millions of records and allows users to create family trees collaboratively. FindMyPast specializes in British, Irish, and Australian records but also includes U.S. materials. MyHeritage combines family tree building tools with access to DNA testing and record collections.
Free resources include the Library of Congress, National Archives, and state and local government websites. The Social Security Death Index, available on multiple sites, lists about 100 million people who died with Social Security numbers. Newspaper archives like Chronicling America allow searching of historical newspapers. USGenWeb provides state and county level genealogical information and links to local resources.
When using online databases, search with variations of names since spelling was inconsistent historically. Try searching with first and last name only, then add state or country. If you don't find someone, try searching with different name variations, nicknames, or maiden names.
Practical takeaway: Start with free resources to learn basic searching techniques before paying for subscriptions. Create accounts on multiple sites to compare what records each one offers. Many sites allow you to upload photos of family members to your tree, making it easier to organize visual materials alongside documentary evidence.
Organizing and Documenting Your Findings
As your research grows, organization becomes essential. Disorganized research leads to repeated work, lost information, and confused family connections. Developing a system from the start saves time and frustration.

Family tree software allows you to enter names, dates, and relationships while automatically creating charts and visualizations. Programs like Gramps (free), Legacy (paid), and RootsMagic (paid) run on your computer. Web-based programs like Ancestry.com, FamilySearch, and MyHeritage store information online, making it accessible from different devices.
Document every piece of information with sources. Note where you found it, what the original document said, and when you accessed it. This is called citation, and it allows anyone reading your research to verify your findings. A source might be "1930 U.S. Census, Cook County, Illinois, accessed on FamilySearch.org on March 15, 2024" or "Marriage license of John Smith and Mary Johnson, dated June 5, 1950, Cook County Courthouse records."
Create a standard format for recording information. Include full names as they appear on documents, dates with day/month/year format to prevent confusion, and locations with county and state or country. When you find conflicting information from different sources, research further to determine which is most reliable. Original records created near the time of an event (like a birth certificate) are generally more reliable than later accounts.
Keep backup copies of your research. Computer failures, accidental deletions, or lost devices can destroy years of work. Save copies in multiple locations, such as external hard drives, cloud storage services, or printed documents.
Practical takeaway: Choose one organizing method and use it consistently. Whether you use online software, spreadsheets, or paper files, standardize how you record names, dates, and sources. Review your system monthly to ensure all new information is properly entered and cited.
