There is another group of Comendadoras ,like those of the Holy Spirit, and Alcantra.
They are found in Spain,though the first name also have monasteries in France where they were founded.The Hospitalier Sisters ofd Sixena in Spain used to wear the Maltese Cross on their habit,and there is some though it might have come from them. Not sure if there are any monasteries of them left. I think they were once members of the Knights of Malta.
In Sitwell’s book on monasteries, they have a photo of the sisters dressed in black wearing a large headress of white which look like it dates from the 14th or 15th century.
Their former monastery now houses another group.
