Relationships

We have been asked on occasions what the relationship is between different members of the family and the following table should be able to show this for any two persons, assuming of course that a relationship exists in the first place. First it is necessary to find an ancestor who is common to them both [CA]. That done, the relationship to [CA] of the first person may be established along the top line and the relationship of the second person (to CA) down the first column. By completing the square, the relationship can be shown. For example, the relationship between a second Gt. Grandson (E1), and a Gt. Grandson (4A), is shown at E4 below as second Cousins once removed.
