Birth, Death and Marriage records are often the best method of making the links to the Brennan Genealogy that will form part of your family tree. Although records vary from country to country, they are normally the most formal record of a person's relations. From the sources below you will be able to find a birth record and, from that, a birth certificate can be ordered which lists the names of the mother and father, taking you back another generation in your tree. A marriage certificate may also list the names of the respective fathers of the bride and groom which may then help you to find them earlier in life on a census record enabling you to fill out more detail in the Brennan family tree.
