There are three relationships recorded. First for me and Shirley, secondly for John, Thurstan, Lisa, Pauline, Michelle, and thirdly for our grandchildren. These are all blood line relationships. They are recorded between [ ] brackets.
The codes used are as follows,
F = Father
M = Mother
S = Son
D = Daughter
Si = Sister
B = Brother
U = Uncle
A = Aunt
N = Niece or Nephew
1, 2, 3 etc = First, Second, Third, etc, Cousin
1, 2, 3, etc, R = Once, Twice, Three Times, etc, Removed
g = Great or Grand
2g = great grand or great great
3g = great great grand or great great great
L = in Law
½ = half
step = step
Example 1: John Edward Olsen = [F;gF;2gF] : Father to me; grandfather to my sons; greatgrandfather to my grandchildren.
Example 2: Albert Edward Olsen = [gU;2gU;3gU] : great Uncle to me; great great Uncle to my sons; great great great Uncle to my grandchildren.
Example 3: Ryan Read = [1,2R;2,1R;3] : first cousin twice removed to me; second cousin once removed to my sons; third cousin to my grandchildren.
The following is from Wikipedia which is very helpful.
Another visual chart used in determining the legal relationship between two people who share a common ancestor (blood) is based upon a diamond shape, and is usually referred to as a canon law relationship chart.
The chart is used by placing the "Common Progenitor" (the person from which both people are descended) in the top space within the diamond shaped chart, and then following each line down the outside edge of the chart. Upon reaching the final place along the opposing outside edge for each person, the relationship is the determined by following that line inward to the point where the lines intersect. The information contained in the common "intersection" defines the relationship.
For a simple example, in the illustration to the right, if two siblings wanted to use the chart to determine their relationship using the chart to the right, their common parents would be placed in the top most position and each child assigned the space below and along the outside of the chart. Then, following the spaces inward, the two would meet in the "brother (sister)" diamond. If their children would want to determine their relationship, they would follow the path established by their parents, but descend an additional step below along the outside of the chart (showing that they are grandchildren of the "Common Progenitor"; following their respect lines inward, they would come to rest in the space marked "1st cousin." In cases where one side descends the outside of the diamond further than the other side because of additional generations removed from the "Common Progenitor," following the lines inward shows both the cousin rank (1st cousin, 2nd Cousin) plus the number of times (generations) "removed."
In the example provided at the right, generations one (child) through ten (8th Great Grandchild) from the Common Progenitor are provided, however the format of the chart can easily be expanded to accommodate any number of generations needed to resolve the question of relationship.
cp = common progenitor g = grand gg = great grand cous = cousin r = generations removed
How to Use: 1. Locate person along top-left row. 2. Locate other person along top-right row. 3. Relationship is where two diagonal rows meet.
