Commonly used Family Tree Abbreviations

You are sure to find many family tree abbreviations in transcripts of Parish Registers, other transcripts, indexes and genealogy books as you conduct family history research. These are unique to genealogy.  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.

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