My husband's father (Paul) and sister (Grace) were adopted from an orphanage called Fitzsimmons House. They were adopted by a German couple: Paul Weible and Wilhelmina Barbara Weible.
Wilhelmina was baptized in the Zion Lutheram Church in 1887.
The children would most likely have been adopted in the 1920's
I think that Paul & Wilhelmina gave them their names, I don't know if the orphanage gave names to the children before being adopted
