Creating Worthwhile Genealogies for our Families and Descendants
NATURE OF EVIDENCE
DIRECT speaks directly to the point in question (e.g., a birth certificate is direct evidence of the date and place of birth of the person for whom it was issued).
INDIRECT or CIRCUMSTANTIAL provides facts from which a conclusion can be inferred (e.g., approximate year of birth can be inferred from the date of an infant's baptism).
TYPES OF EVIDENCE
PRIMARY personal testimony of an eyewitness or a record created shortly after the event by a person with personal knowledge of the facts
Applying the answers to those questions:
Death information provided by the attending physician is primary evidence of the date and place of death, but birth information on the same certificate (provided by someone with no personal knowledge of the date and place of birth of the decedent) is secondary evidence.
SECONDARY Evidence that is copied or compiled from other sources or that is written from memory long after an event occurred.
Records: Family Bibles, vital records, correspondence (letters), memoirs, journals, diaries,
unrecorded deeds and wills, diplomas, certificates, and testimonials.
Public Records: Censuses, government records, military, pensions, land bounty records, passport applications, passenger lists, original grants, naturalization or immigration records, records of entry, state, province and local records.
Institutional Records: Church records, cemetery records and inscriptions, educational institutions, societies and fraternal organizations.
Printed Materials: Family histories, collected genealogies, source materials [abstracts and transcriptions of records], local histories, other printed materials such as newspapers, reference works and directories (city, telephone, trade and professional), websites, Mailing Lists, Message (Bulletin) Boards, and e-mail messages.
Manuscripts: Commonly refers to handwritten or typed, not professionally printed, works.
The best form of evidence is the original document or record.
When an original document is not available, a legible scanned copy, photocopy, or microform (film or fiche) copy of the original document should be obtained.
If an original document is not extant, one must rely on the official transcript of a document (such as a deed or will) entered in a record book by the clerk.
One should not rely on an unofficial transcript of, extract from, or abstract of an original document if the document itself or a copy of it is available.
Family historians must learn to weigh and evaluate evidence similar to the way juries do. There are differences, however.
In a court of law there are two major categories of evidence:
Admissible; meaning it is worth considering, but still varies in degrees of reliability.
Inadmissible; meaning it is not allowed to be heard because it is not reliable enough.
But we genealogists do not have judges to tell us what can or cannot be heard. We "hear" it all. We look at every shred of information we find and sometimes draw incorrect conclusions because we do not know how to weigh it or how to resolve the frequent occurrence of conflicting evidence.
Researchers often assume that if several pieces of information agree, the data must be correct. Such assumptions often lead to erroneous pedigrees and frequently create genealogical dead-ends. There is a great deal of confusion surrounding the terms "evidence," "proof," and "sources." Donn Devine, a certified genealogist and practicing attorney, in an excellent article on "Evidence and Sources" in Ancestry magazine, provides this guidance:
Source is the means by which information comes to a researcher.
Evidence is the physical form in which information is presented to the senses.
Proof is a name for a process that takes place in the mind, not for the evidence on which it is based. However, the term is also used to refer to the documents utilized as evidence for many lineage-society applications.
Family historians should be cognizant that most genealogy software programs use predetermined terms in their report format, such as "married" that may or may not be 100 percent accurate. The compiler may or may not have overridden default options or included footnotes to indicate variants. In this instance (above) the term "married" is used (FN16) and that is how the relationship was referred to in the sources so cited. Nevertheless, research in primary sources has not turned up a marriage license or record to either the first or third "wife" assigned to Virgil Earp.
Remember to cite the specific sources you actually used in compiling your family history.
"Source notes have two purposes: to record the specific location of each piece of data and to record details that affect the use or evaluation of that data." (Evidence! Citation & Analysis for the Family Historian).
After collecting information, take a careful look at what you have and sort it into two groups:
Primary evidence or sources. These usually are written records; the first or earliest documents in which a particular piece of information was recorded, and created at or near to the time of the event.
Secondary evidence or source. Think of this as second-hand information that has come from some other person or record.
Get as close to the primary records and original documents as you can. However, keep in mind that even they may contain errors. Just because it is a primary source does not guarantee the information is 100 percent correct, but it is more likely to be. Additionally, make the effort to trace your secondary evidence back to primary sources. Don't blindly accept information you find in a book, CD, or on the Internet or from your relatives' memories.
How do you resolve conflicting evidence?
Follow the advice of Thomas W. Jones, Ph.D., CG, given in a National Genealogical Society Conference lecture: Judge Each Item of Evidence with the test of the four "Cs":
Closeness (in place and time).
Credibility (of person who made the record).
Causality (why the record was made).
Corroboration (with other evidence).
Of course, if you do not know where the information came from, how can you evaluate it? That is why you should carefully record and cite your sources. To create worthwhile genealogies for our families we need to use the best records and sources available, do the best work we can so our family histories may be continued by our descendants, and so they will not have to duplicate all of our work because they do not what sources we used to reach our conclusions.
