To some people, this is a source of frustration as the difference between the two is clear. For others, there is no difference and their interchangeability is acceptable. With this in mind, we ask whether there is a difference and if it matters.
The simplest way to explain the traditional difference between the two terms is that genealogy is a subset of family history.
Wikipedia defines genealogy as:
The study of families and the tracing of their lineages and history.
Wikipedia then goes on to define family history as:
The systematic narrative and research of past events relating to a specific family, or specific families.
