My extended version

---

The Soundex coding system was patented in 1918 and 1922 by Robert C Russell and Margaret King Odell. A variation was used by the WPA during the 1930s to index like-sounding names found on the 1880 census. This helped researchers identify misspellings and other common variations of surnames.

It works like this:

For STRATTEN

• Preserve the first letter
  STRATTEN
  
• Strike out the 2nd of consecutive consonants
  STRATTEN
  
• Stike vowels (other than the first letter)
  STRATTEN
  
• Code the first three remaining consonants
  STRATTEN
  which becomes S363
  
  But the N is left out. My system codes all remaining consonants:
  S3635
