Soundex is a phonetic index that groups together names that sound alike but are spelled differently, ''for example'', '''''Stewart''''' and '''''Stuart'''''. This helps searchers find names that are spelled differently than originally expected, a relatively common genealogical research problem.

The indexing system was developed by Robert C. Russell and Margaret K. Odell. It was patented in 1918 by Russell, and again in 1922 by Russell and Odell. It is formally called the Russell Soundex, and a variation used on the censuses is called the American Soundex.<sup>1</sup>  
The indexing system was developed by Robert C. Russell and Margaret K. Odell. It was patented in 1918 by Russell, and again in 1922 by Russell and Odell. It is formally called the Russell Soundex, and a variation used on the censuses is called the American Soundex.<sup>1</sup> When a computer was used to generate Soundexed index card for a census it was called a Miracode, and the information listed was slightly different from handwritten Soundex cards.


It was most famously used on parts of the 1880, 1900, 1910, 1920, and 1930 United States federal censuses. It is also used by the federal government for selected ship passenger arrival lists, certain Canadian border crossings, and some naturalization records. A few county governments have also used a version of Soundex for courthouse kinds of records. More recently, Ancestry.com and other Internet companies have featured a Soundex search for their huge online genealogical databases.

'''Unrelated names may be grouped together.''' Sometimes names that do not appear to be related show up together on a Soundex index. Ignore clearly unrelated names. For example, if you were looking for '''Wilkins''', you may also find under the same Soundex code, W425, the name '''Walakynowski'''.

'''Related names may not be grouped together.''' Sometimes names that are obviously related do not come together in the same Soundex index group. For example, '''Clausen''' is under C425 and '''Klausen''' under K425. If you cannot find a name you seek in a Soundex index, there are 20 alternative ideas in the Wiki article [https://wiki.familysearch.org/en/Guessing_a_Name_Variation Guessing a Name Variation] to help find elusive names in indexes.
