Family Research is the most important Starting Point!
Genealogy involves intense family research, depending on how far back you want your family tree to go. While most of us know who our parents and grandparents are - sometimes also our great-grandparents - not many of us can indentify older family members without doing some thorough family research. But before you start doing any family research, you do need to have some idea of where you are going and what your aims are.
This may sound a bit strange, because clearly anyone wanting to build a family tree will want as much information as possible about their family. But in fact it is a lot easier to tackle a family tree in sections. For instance you might start with your father's side of the family, and then stick with the paternal line. Or you might start with one set of grandparents and see how far back you can go on both sides of the family. It can get quite confusing if you try to find out too much, too quickly, about anybody and everybody who finds a branch on your family tree. You'll probably be amazed how many different names you come up with - because of marriages.
People who have done some sort of research before will usually find it easier to tackle genealogy projects, even if they have never tackled this type of subject matter before. If you have never done any type of research yourself, it can be mind-boggling trying to find a place to start. Like everything in life, if you work progressively, you will eventually get to your final goal, even if it does take a bit of time.
The very basic information you will need in a family tree will be birth and death dates, as well as marriages. All these will, of course be linked to certain names and places. If you can find out more about any of your ancestors it will make the task all the more interesting, but it isn't essential to the tree.
Having a ready-made template of some type makes evolving a family tree a lot easier, but it never takes the place of family research.
