How To Find Out If You Have A Coat Of Arms Or Link To A Coat Of Arms

How can I find out if I have a coat arms or link to a coat of arms?

There are various ways you can find out if you've got a coat of arms. The College of Arms is probably the best place because they hold all the records related to heraldry and a huge number of pedigrees and family trees. It'll be based mainly around your surname, so you can always ask one of the heralds to do some research for you in their records, if you suspect you've got a good claim. But then there are the various publications such a Burke's Peerage, or DeBret's Peerage, which show you the existing families that are able to bear coats of arms and then you can start to do some genealogy to see whether you can then prove a connection to those families.
