When you start looking at individual family branches, the pattern for each family is different. One family might have 3 children while another family might have 10 children. Some of the children will be married while others will be single.<br>
Before you can establish a logical coding system for your family branches, decide what you want to achieve. A pedigree chart is an '''ascending''' form starting with yourself, and only notes direct ancestors. A '''descendancy''' chart starts with a certain ancestral couple and comes “down” to you and living generations, including all children of all children. There are many variations on such charts.
Here’s an example... If you wish to follow the family branches of your great-grandparents to include all your living relatives, here is the appropriate numbering sequence.<br>
Ask three or four genealogists how they code ancestors’ descendants, you will probably observe different methods. Choose one you feel comfortable with and be consistent in using that method.<br>
When using the reference number on subsequent forms, add FG to the code originated on the Family Group Record forms. We will discuss the form later, but suffice to say that this will be where you will initially list all descendants.
The generally accepted systems in North America for numbering descendants are either the “Register method” or the “NGSQ” method. Examples of these are continually featured in ''
The New [http://www.americanancestors.org/home.htm England Historical and Genealogical Register]'' and the ''[http://www.ngsgenealogy.org/ National Genealogical Society Quarterly]'' — flagship journals for self-education through the study of their scholarly articles. More information about the two societies which produce these journals can be found at their websites.<br>
