As per the following cousin charts, when two siblings in one family marry two siblings from another family, and each couple has a child, these children will be called double cousins. As you can see from the Double Cousins Charts, double cousins are more genetically related than first cousins because they share not only their maternal D.N.A. but also their paternal D.N.A. In addition to this, double first cousins are first cousins because they share both sets of grandparents. With the help of EdrawMax Online, creating such extensive double cousins charts are very easy as the tool comes with free templates and vector-based symbols.
