In that article, I described the process of locating the correct place where records may be maintained. That included using maps and determining what geopolitical organization was responsible for governing the place at the time that records were created. I received a number of responses to that article.
Genealogy is a methodical study that seeks to document lines of descent of a family or families.
In most cases we use written and recorded records. In other cases we may use word of mouth, i.e., family traditions. But what is most important is that we document our research and resources so that someone else can easily retrace our path more easily. That might include our descendants or, if you're seeking admission to a society such as the D.A.R., it may be a committee of some sort. Genealogists have been looked down upon by historians and academicians precisely because so many genealogists do not document their sources or do so sloppily.
