X is for "X" a Signature Mark
In earlier centuries, many people signed legal documents not with a written signature but with a simple "X." Far from being a sign of ignorance, this mark carried full legal weight and was witnessed and certified by others present at the signing. Literacy levels varied enormously across time and place, and many respected and prosperous members of their communities signed with a mark rather than a written name. Finding an "X" on a document is a reminder that
our ancestors' lives cannot be measured by their ability to read and write.
For genealogists, a signature mark can be a useful research tool. If your ancestor consistently signed with an "X," you could use that as one way to distinguish them from another person of the same name who signed with a written signature. Marks also came in varieties beyond the simple "X" — some ancestors used a distinctive symbol, initials, or a personal mark that appears consistently across multiple documents, which confirms that you are following the right person through the records.
Maryland's colonial and early national records are full of signature marks, particularly in deeds, wills, and court records held by the Maryland State Archives. Seeing the actual mark your ancestor made on a document — however simple — is one of those quietly moving moments that reminds us why we do this research.
Tip for beginners: When you see an "X" or other mark on a document, look carefully at the witnesses named alongside it. Witnesses to a signature were often neighbors, friends, or relatives, and their names can point you toward new research leads.
Tip for experienced researchers: When transcribing a document where your ancestor signed with a mark, note it carefully in your research log rather than simply recording the name. Distinguishing between a signed and a marked document can be an important detail when building a case for or against a particular identification.
Now it's your turn! Have you ever found an ancestor's signature mark on a document — and did it change the way you thought about them or their life?
