Soundex for St. Clair, 1900, Missouri

[CMelahn@aol.com]

Anyone have experience with soundex code for St. Clair for 1900 U.S. Census?

I believe the code is S-324. I looked through the entire set of this code for 
State of Missouri, 1900 Census but found no St. Clairs.  Either I have the 
code wrong, or there were no St Clairs in Missouri in 1900, or ???

Anyone able to comment? Experience with soundex?  Know of St. Clairs in 
Missouri in 1900? 

Thanks for helping me with this puzzle,
Chris
