We are also looking for information on that same home. My grandmother, Rachel Gauna, and two of her sisters (Amelia and Anita) were there with her. Rachel was the youngest and was allowed to leave after her 16th birthday, which would have been in July, 1919. We're not sure when they arrived. I've had little luck finding anything on the home, but I did find a reference to a:
House of the Good Shepherd
For problem and delinquent girls operated by the Catholic Sisters of the Good Shepherd. Records may be at the Department of Institutions. Can also check with the Archdiocese of Denver
We're going to check this out with the archdiosese and see what we can find.
