What is a Second Cousin

 Contributed to Ayrshire Rootsweb  


 

 


Siblings (brothers and sisters) who share a set of parents. 

 

First cousins are persons who share a set of grandparents (but aren't siblings).

 

Second cousins share a set of great-grandparents (but aren't first cousins or siblings).

 

Third cousins....g-g-grandparents, etc.

 

"Removed" is used when two persons share a set of ancestors but are not the same number of generations in descent from those ancestors.  For example, the children of your first cousin would be your first cousins, once removed (the common ancestors are your grandparents, who are their great-grandparents).  Your children and your first cousin's children would be second cousins.   

This can go way back.  For example, if I were descended from a brother or sister of Julius Caesar, then I would be a great, great,......, great nephew of Julius.  If I descend from a first cousin of Julius, I would be Julius's first cousin, many, many times removed. 

In the beginning you'll feel as if you need to get an online degree in genealogy, but once you get it, it actually isn't that complicated.  


A Chart for Figuring Relationships

 

From CompuServe's Genealogy Forums

On the top row, find the relationship of one person to the common ancestor and follow the column straight down. Find the other persons relationship to the common ancestor on the left hand column and follow that row straight across. The relationship is where the projected row & column meet.
