In reading Astor the Rise and Fall of an American Fortune by Anderson Cooper and Katherin Howe you may not think there are Sioux Falls South Dakota connections to the famed Astor family but there are 

With Sioux Falls being along side the Big Sioux River in the wild prairie of the Dakota Territory we have a deep connection to fur trading history and fur trading is where John Jacob Astor starts to make his fortune. So its makes sense that Sioux Falls is on the map for the Astor family.  

In the 1880s John Jacob Astor the 3rd donates 20 thousand dollars which would be well over 600 thousand dollars today to build a church and wants it named in honor of his late wife Charlotte Agusta Astor. Bishop Hare takes this money and the corner stone of the Church of St Agusta is laid in 1888 

However, once the church is built Bishop Hare invites Calvary Church to worship there and over the years the name morphs into Calvary Cathedral 

This wont be the only time Biship Hare takes money from an Astor and only sort of does what they ask. In the 1890s Maggie Astor De Stuers comes to Sioux Falls and a devout woman she goes to the Church of St Agusta as it is named for her aunt while there she makes a donation for several stained glass windows to be made in honor of deceased loved ones. Bishop Hare takes the money, he even gets the windows made, but when he finds out Maggie is in town to obtain a quickie divorce he refuses to hang the windows.  

The legend goes at some point Bishop Hare is out of town and someone else hangs the windows, when he comes back and sees them he pulls a ladder over and scratches out the dedication names on the window. The windows still hang with scratched out names. 

In 1909 Bishop Hare dies and is buried on the property at Calvary cathedral.
