Gary,
I am happy to help - normally, I don't do so much gratis but I had the opportunity and time. I don't think you are going to find anyone who has done research yet. I did find someone on ancestry.com who had John Weber (1871-1919) in their family but they didn't have what I had already found.
So, that means you will likely have to do the research yourself or hire it done. The good thing is that I have already provided you key info:
1) Look for the remaining Weber children in the baptismal records of Ss. Peter & Paul Catholic church in St. Louis - I believe these records are available through the LDS.
2. Obtain Adelheid (Schmidt) Weber Krohne's obituary from the St. Louis Post Dispatch.
3. Start searching for the Weber and Schmidt families in St. Louis.
