To read the charts which are included with each Family section, start at the left hand side. This is the most recent time period. As you go towards the right on the chart you are going back in time. Each marriage is grouped in a "c" shaped bracket and any children from this marriage (or partnership) will be a line extending out from the left hand side. As a convention, I put the male on top and female below in the marriage bracket. Children's lines extend out to the left with the oldest child on top and then descending in order of birth. Some charts will have a married couple who are the focus of the chart. You will then see multiple children and grandchildren to the left of the chart. Otherwise the charts show a couple and the child from which the immediate family is descended to the left. Other children of the couple will be ignored in this case. The charts in general are following the path of the DNA as it spirals into the future generation after generation.
The following chart illustrates this. All of my charts will follow this general organization.
