I don't know a whole lot on this subject,but maybe this will help.
The Sisters of the Holy Family of New Orleans ,the Oblate Sisters of Providence,and the Franciscan Handmaids of the Most Pure Virgin Mary were founded as black communities.
Especially in the early 1800s it was very hard for a black woman to join a community,though there may have been a few who managed to.
Even the founders of the first two religious communities had their problems due to the racial issue.
And while a black or other candiate to the sisterhood was encouraged to join whatever community that would accept them, even in the 1960s and 70s they had problems.There is an orginazation for black sisters,but i can't recall the name right now.
I don't know how asian or mexican sisters have faired in that regards.
At various times Mexico has had several revolutions,and priests and nuns came toSan Antonio.There are several communities here in town who are Mexican and have been here for many years.In this area since the majority of hispanics are Catholic,and that there are many prominent hispanic families here since the founding of the city,there may not have been the racial problems that black sisters experienced,or to a very minor degree.
The Sisters of the Holy Spirit and Mary Immaculate were founded by Mother Margaret Healy-Murphy.She was a widow ,her husband had been mayor of either San Antonio or Corpus Christi.
She founded the sisters to teach blacks and hispanics,and opened St.Peter Claver School for blacks.She had her problems in regards to what she was trying to do,but evently won out.
Their motherhouse is on Yucca Street.
There was even an attempt to found an order of native american sisters,but the community did not last for various reasons. I can't recall the link for info on this.But just google it and something may come up.
By the way I love the kitty nun.Looks like my old cat Blackie.
