Genealogy is the study of your family tree - it's like a big map of your family, going back many generations. It involves research and detective work to figure out how everyone in your family tree is related to each other. For example, if you have a grandma, grandpa, mom, dad, aunts and uncles, you can use genealogy to figure out how they are all related to each other. To do this, you need to think like a detective - ask lots of questions, and use resources such as family photos, letters, birth and death certificates and old newspaper articles. All of these can help you figure out who is related to who in your family tree.
