We can help with this by looking in our library of Heraldic books. We use Fairbairn’s Book of Crests. There are many editions of this unique reference book which was first published in 1859. You can normally find a copy in your local library, should you wish to do your own research. Most family crests are detailed in this book and we would be more than happy to send the options to you by email.
Or you can visit the website and fill out the Crest Finder form:

Your family crest can be engraved on your signet ring either in reverse or for sight. The traditional way is in reverse so that it is the correct way when it is pressed into wax to make a seal. This is where the term seal engraving comes from.
