group of people on the same horizontal line represents a separate generation. Most people are familiar with these terms, but these are all close family members, and you will be working many generations back into the past when it becomes harder to keep track of distant relationships; so listed below are some of the key words used to describe relatives from the extended family, and ancestors further back in time, which are perhaps less familiar.
Blood Relations
The direct line in your family tree is made up of all the people who have been biologically crucial to your creation. Therefore they would include your parents and your grandparents, but not any of their siblings and other descendants – these people are your extended family. Each time you move one generation further back, you need to add ‘great’ as a prefix. Therefore the parents of your grandparents are known as your great-grandparents, and the parents of your great-grandparents are your great-great-grandparents, and so on. Every time you search for another generation in your direct line you will be looking for twice the number of people as the generation that came after that. This is because you have two parents, who each have two parents, so that you have four grandparents. These four grandparents have two parents each, which means you have eight great-grandparents, and then sixteen great-great-grandparents. As you work further back than this, you might find it easier to shorten this description to ‘2 x great-grandparents’.
Extended Family by Blood
These are the people that are related to you by blood, but are not biologically crucial in your existence today. Where possible, you should include them in your family tree – particularly after your first phase of research – but you might want to focus on your direct ancestors and come back to them at a later date.
Nieces and Nephews
Your nieces and nephews are the children of your siblings. Niece is used to describe a female offspring and nephew to describe a male offspring. Any subsequent children of your nieces and nephews are known as your great-nieces and great-nephews, and another ‘great’ is added to the prefix each time another generation is born.
Uncles and Aunts
Your uncles and aunts are the siblings of your parents. The siblings of any previous generations in your direct line are described by adding ‘great’ as a prefix, and each generation you go back another ‘great’ is added. Therefore the siblings of your grandparents would be your great-uncles and great-aunts, and the siblings of your great-grandparents would be your great-great-uncles and great-great-aunts. Some people use the word ‘grand’ instead of ‘great’, and might describe these relations as ‘great-grand-uncles and aunts’.
‘This is your family tree, so everyone else is described in terms of their relationship to you.’
Cousins
Your cousins are the children of your aunts and uncles. These are known as your first cousins. Any subsequent descendants of your first cousins are indicated by how many generations they are ‘removed’ from you. If your first cousin has a child, this child is your ‘first cousin once removed’. If your first cousin then has a grandchild they would be your ‘first cousin twice removed’. First, second and third cousins can only be used to describe cousins of the same generation. Therefore, if you had a child, they would be second cousins with your first cousin’s child. This means that while you refer to that relation as your first cousin once removed, your child would call them their second cousin.
To describe the cousins of any previous generations to yourself, you should refer to them as the cousin of whichever person in your direct line they are of the same generation as. This means that the parent of your second cousin should be called your ‘parent’s first cousin’, and the grandparent of your third cousin would be your ‘grandparent’s first cousin’. The relationships between cousins is very confusing and you may find that in documents such as wills and census returns people use the word cousin to describe a distant relative without qualifying exactly how they are related. It will be your job to untangle this confusion!
Extended Family by Marriage
Families are complicated entities, and as well as direct blood relatives and their extended family you will quickly discover that there are other relationships that are more complicated to define – usually the result of divorce, subsequent remarriage and an associated second family. Here are some of the more useful terms that you may need to incorporate into your family tree.
In-laws
When one member of your family marries, they are related to their partner’s family as a result of the wedding. This relationship is said to be ‘in law’ due to the legally binding nature of the union. Thus the mother of the bride is the ‘mother-in-law’ of the groom, just as the father of the groom is the ‘father-in-law’ of the bride. If either the bride or the groom has siblings, then they become the sister- or brother-in-law of the other party.
Step-relations
The word ‘step’ is used to describe the relationship to a member of your family that occurs through a subsequent marriage by one (or indeed both) of your biological parents. Your stepfather would be your biological mother’s husband from a subsequent marriage, whilst your stepmother would be your biological father’s wife if he married again. If either of your step-parents had children from a relationship prior to marrying your biological parent, these children would be your step-brothers and stepsisters; whilst they would be described as your biological parent’s stepsons and stepdaughters.
Half-relations
The word ‘half’ is used to describe a relationship between children who share only one biological parent. For example, if your biological father or mother had a child with your step-parent, this child would be your half-brother or half-sister.
Drawing Your Family Tree
Using these terms, you should be able to build your initial family tree quite quickly; and it should display all the information you’ve found when you were interviewing relatives and looking through collections of family heirlooms. There are bound to be some things that you don’t know yet – full names and biographical dates of more distant ancestors, for example – and you should add question marks against anything you’re not sure about. This is one of the main purposes of this first family tree – to show at a glance what you need to verify, check or research more fully. Don’t worry if it looks messy at this stage or a bit sparse – you’ll be tidying it up and adding new branches when you start your research away from the family.
One thing to decide upon is the presentation style of your family tree, bearing in mind there are several recognized ways of doing this and the final choice will be down to you, based on what you find easiest to work with and how much data you wish to include. Some trees will only show the direct line, whereas others are very large and sprawling, and include all the siblings in each generation and distant cousins.
In the past, genealogy was the preserve of the aristocracy – or those that aspired to higher social rank – who wished to prove their connections to illustrious forebears. They commissioned diagrams, or ‘pedigrees’, that were as much works of art as family trees, with coats of arms, heraldic beasts and key names circled. A pedigree that shows immediate ancestors as far back as the
