Before You Start Your Family Tree

By Dr Nick Barratt
Blood relatives

Frederick and Margaret Hall, and their four children
The Halls and their four children, c.1905  
As you've now seen, the family tree defines people in terms of their relationships with one another and particularly with you, the researcher. Most of the words used in family trees are familiar ones, used every day, such as father, mother or brother, sister, son or daughter. The following glossary lists these to help you to describe the relationships between family members who are related through blood (as opposed to marriage).

uncle the brother of your father or mother
aunt the sister of your father or mother
sibling your brother or sister
cousin the son or daughter of your uncle or aunt
second cousin the son or daughter of either parent's first cousin
nephew the son of your brother or sister
niece the daughter of your brother or sister
grandfather the father of your father or mother
grandmother the mother of your father or mother
grandson your child's son
granddaughter your child's daughter
great grandfather the father of one of your grandparents
great grandmother the mother of one of your grandparents
great uncle the uncle of one of your parents
great aunt the aunt of one of your parents
