Genealogical Relationship Chart

Instructions:

  1. Select two people in your family and figure out which ancestor they have in common.  For example, if you choose yourself and a first cousin, you would have a grandparent in common.
  2. Look at the top row of the chart (in blue) and find the first person's relationship to the common ancestor.
  3. Look at the far left column of the chart (in blue) and find the second person's relationship to the common ancestor.
  4. Move across the columns and down the rows and find the row and column containing these two relationships (from #2 & #3) intersect.  This box is the relationship between the two individuals.

If you need to go deeper, examining the chart should reveal the pattern, and then it can easily be extended to as many generations as you wish, in either direction (additional rows or columns).

If anyone is interested in a downloadable version of this chart (probably as a PDF) notify the Web Master and, in a day or two, one will be made available here on the Web Site.
