Genealogy is something that people have done for centuries, if not longer. The need to know about your past is a natural, human curiosity and for there have been many different people that have strived to learn as much as they can about their past throughout history.
However, genealogy was done in olden times for those in power. For example, it was important to trace the genealogy of nobles, kings, queens and emperors. Any ruler needed to have information that showed that he was the right ruler for the job. Genealogy helped decide who the righteous ruler often was.
If you wanted to claim that you had the right to have wealth and power, then you had to show that your ancestry proved that you were worth it. Showing that you were the rightful heir or the rightful ruler was no little task and only genealogy could make this happen.
On a side note, the coat of arms of a family in the times of royalty where often used to help decide family lineage, called heraldry. The ancestry of royalty enabled quartering the coat of arms for a family.
Often, though, modern ancestry studies have shown that many of those that used these methods to “claim” their righteous place in royalty where not genuine. They were merely untruths that did not prove anything. The most notable of these, of course, are those kings, emperors or other rulers that used their ancestry to show how their heritage to gods and the founders of the civilization itself.
Genealogy is something that is traced through truth, and that is something that is in the eye of the beholder. While you can probably find documentation to support modern claims of ancestry, going back far in time is difficult.
Nevertheless, it is a story that you can tell. Imagine begin able to say that your great, great, great-grandfather was part of the Royal Family.
The search for answers, then, will start with the need for accurate answers. For that, we turn to modern methods of uncovering the truth of families, first.
