Commonly used Family Tree Abbreviations

Family Tree Abbreviations

Family tree abbreviations are shortened versions of words or phrases, and are utilised because they are easier to use, especially on a family tree when space can be at a premium.

You are sure to find many family tree abbreviations in transcripts of parish registers, census returns, other transcripts, indexes and genealogy books as you conduct family history research.

These abbreviations are unique to family history research and genealogy, and may not be found in any other fields or industries.

When you peruse a family tree, you will probably see the letter b. or d. before a date, which stands for born or died.

You should ensure you do not cause confusion when compiling your tree. 

When using family tree abbreviations, it is prudent to use b. for born, bap. for baptised, m. for married and bur. for buried, and use this abbreviation throughout your family tree.

If you use a single letter to signify a surname such as D for Dunkley on your work, you should use the same letter(s) on every document and also include a description of what it means.

This will help other people to understand what you have written and makes it easier to remember the letter(s) you have used.
