I found this amazing monument at Bellefontaine Cemetery in St. Louis, MO.
I had to email the Cemetery to get the information to who was resting beneath this monument. Here is the information they sent me.
Georgiana C. Louderman
Lot 1697 Block 82/83 Space 4.
On the fondation of this monument (the gray portion) in the corner it has "Fisher & Bird" below that "N.Y." I found an ad for the company in the "Real estate record and builder's guide, Volumes 5-6".
I am also taking a guessing that the foundation may have been a later addition. It looks much newer then the rest of the monument.
