Evidence Analysis

Death Certificate of Patrick J. Moughty, 1973,

Last week I discussed source citations.  As we look at various sources, be they books, certificates, census records or other artifacts, we are gathering evidence from them and it’s therefore important that we understand what we’re looking at, why it was created, and where the information contained in that source came from.  As genealogists and family historians, our goal is to find original sources… (1) documents that were created at the time an event took place (2) by someone with first hand knowledge of the event.  We’re not always able to find original documents, but that is the goal to support our research.  If a source does not meet the two criteria listed above, it is a derivative source. The fact that a source is original doesn’t mean the information contained in it is correct.  My father-in-law's original birth certificate spells his name incorrectly. 


    The third concept is of evidence...direct or indirect.  Direct evidence provides the answer to our research question. If our research question is "who are the parents of Michael Daly?" a birth certificate with the name of his father and mother provides direct evidence that answers the question.  Sometimes there is no direct evidence available and we need to gather information from multiple sources and write a proof summary presenting the indirect evidence from sources not directly related to the question we are trying to answer.  I needed to prove James who died in New York was the son of David who died in Connecticut but there was no extant birth or baptismal record.  By following James’ land deeds through three New England towns, and two states, along with David's probate documents I was able to prove that the James was in fact, the son of David.

    If you are new to genealogy, one of the first things you’ll look for are home sources.  So what original documents might you find?  Birth, death or marriage certificates, naturalization papers, newspaper clippings, obituaries, a family bible, deeds, photographs, military records, legal records, church records...you might find any or all of these plus more.  Or, if you family was like mine, you might find nothing.   This is where you want to hope that you are descended from a bunch of pack rats. 


    Let’s look at the information contained in the death certificate.  In the first section we have the name of the individual, the date of his death and the place of death, all primary information.  The rest of the information, however, was provided by an informant, in this case, Mrs. Christine Dennis (his daughter). She was not there at her father’s birth, so she only has secondary information about the events...the information could be right or wrong.  Notice that the name of Patrick’s mother was listed as Mary “Unobtainable.” Christine didn’t know her grandmother’s maiden name.  This document does provide us with a clue to Patrick’s birth, 25 Oct 1889 in Ireland, but we need to find further evidence to confirm this information.

The next section of the death certificate is the medical information.  In some states (including Florida) this information is only available to family members and you must request the “long form.”  This information is vital in creating a health history, so make note of the information you find.  Patrick’s doesn’t give a great deal of information as he died at home and the death certificate was completed by the medical examiner.  If Patrick had died in the hospital, or if his personal physician completed the death certificate there would likely have been more information.




You can then add the information to your genealogy database or online tree.  We learn from his death certificate that Patrick was married at the time of his death to Beatrice King (as opposed to being a widower); that he was a naturalized US citizen; that he was a retired chauffeur for Electrolux Corporation; his address at the time of his death; that he was not a veteran and that his parents were Bernard Moughty and Mary (?).  He died of heart failure and was buried at St. Mary’s Cemetery in Greenwich (which also tells me his religion was Roman Catholic).  Based on the above information, what would be your next research steps?

   Next week I’ll share where this document led me.

   Happy Hunting!
