I am trying to find some record of Kathryn T Sullivan (great grand mother) who was born in Iowa around 1871. When her father died (her age 10-12) she was sent to an "Ursuline Convent", most probably in Iowa, where she resided until age 18. I find her in the 1900 Federal Census (married with children at that point) and I find an almost certain sister living in Cedar Rapids, IA, in the 1880 Federal Census. I am puzzled why Kathryn does not show in the 1880 Census but am assuming that is somehow an artifact of living in the convent. I know of the Iowa Soldiers' Orphans' Home (later Annie Wittenmeyer Home) but the Wikipedia entry mentions no association with the Ursulines.
Does anyone know of a convent, orphanage, or maybe school in Iowa that was operated by the Ursuline order? Would there be any records available from the Annie Wittenmeyer Home which closed in the 1970's?
