How would you find a nun's birth name?

Question

Are there any general church records where they are recorded? Aside from convents, I keep running across them in orphanages but don't want to make a profile with a very slim chance of connecting to the tree.

Answer 1

Do a google search for “women religious records” and you will find a large number of resources for records of the various religious orders, some of which are open to researches. I do not know if what you seek is available, you would need to contact the specific order.

In some of the diocesan Catholic Church records from Mexico, which are online  at FamilySearch, there are records pertaining to men taking holy orders, which can include family histories. This is different from the women becoming nuns, as women do not take holy orders.
