Begin your search for family history by exploring these resources and research strategies.
Your family tree begins with you. As you climb the family tree, you will move from the present to the past adding each branch.
Keep an open mind and be ready for every possibility. Ancestors were only human. Their stories are as broad and varied as those of the people living today.
Keep track of the sources you use and give credit where it is due. Local and family history research requires you to access and evaluate numerous original and published records in a variety of repositories and collections.
If an online tree or published book includes your lineage, make note of it and give the researcher credit for any help their work provides you, but always do your own research. It's very important to review every record and relationship for yourself.
Interview living relatives, family friends, and others who knew your family well.
In genealogy, we start with ourselves, then add names, dates, and facts that can be verified with reliable records. We work backwards in time from relationship to relationship and generation to generation. This way we build a documented chain of evidence from ourselves to our ancestors.
Take some time at the beginning of your project to review the documents you already have, what you already know, and how you know it. Be sure to cite your sources clearly and consistently. Decide on your research strategies and how you want to record your progress. Keeping a research log helps to avoid duplication and save time. By keeping track of your work, you can easily share your progress and explain your conclusions.
Define your questions and your goals. What are questions do you want to answer? What questions belong to another project? How will you share and preserve your research results?

The following links to online records highlight just a few of the most foundational sources that we can use to begin our research.
Personally visit the cemetery to read tombstones and to see which family members are buried together. If the cemetery has an active office or board, ask them for burial records that may provide additional information and enable you to identify any unmarked graves.
For distant locations that you cannot stop by in person, search online databases such as: Billion Graves External and Find a Grave External. These sites are based on volunteer submissions and are not necessarily complete. As you locate the graves of your relatives, you can add or improve their entries in these free databases.
Find your family in the 1950 U.S. Federal Census and continue backward decade by decade. Free access to Census records is available on sites such as FamilySearch External.

Newspaper articles are a great source for local and family history. In addition to obituaries and marriage announcements, you may find a variety of headlines and social mentions that provide insights into the daily life of your ancestors and their community.
The Library of Congress provides free access to Chronicling America, a collection of historic newspapers. If the newspapers for your area have not been digitized yet, use the U.S. Newspaper Directory to see which repositories house the archives. You can also access further resources about available publications through the Library's Newspapers and Periodicals Division.
State, county, and community level research is essential in the pursuit of family and local history. Become familiar with the repositories in the areas where your ancestors lived: academic archives, courthouses, genealogical / historical societies, libraries, and more. Keep in mind that most records have not been digitized. It is critical to directly contact the institutions that may hold records important to your investigation.
A quick reference to locate local records is the Red Book: American State, County, and Town Sources External. Online guides such as FamilySearch Wiki External are also great tools for tracking down available records in particular places.
