From that same screen, after you uncheck the "Allow XXX to edit family", you can copy the link a little bit lower on the left sidebar and send it to however many people you'd like. Note that the family will be centered on whichever family member you have selected when you click the "Share" button. It might be useful to change an ancestor from dead to alive temporarily so that you can share from that common ancestor if you don't have someone more appropriate to use to share from.
