The definition of genealogical research is “the study or tracing of lines of descent,” more commonly known as discovering your family history. While that is true, to document and understand family history, one also needs to research and understand the historical context in which ancestors lived. Genealogists often encounter documents that link their family history to significant historical events and time periods. When these elements are put together, the lives of one’s ancestors more fully take shape.
