If you have a chronology for an ancestor and, during their adult lifetime, you have five year gaps where you are not certain where the ancestor lived or what they were doing, try and locate a record to provide that information. Answering those questions may help you determine more about where the ancestor was from and what her origins were.
Did they head west?
Were they in an institution?
Did they have a financial setback?
Did they have a “short-term” marriage that did not last?
