In my opinion, Sr. should NOT be entered in the prefix box. She is not "Sr. Bernadette." Bernadette is the only name that should be in the first name box. Middle iniital P should not be in the first name box, but rather in the Middle Name box. I believe Sr. Catherine Marie should be in the nickname field. I actually edited it to that format. However, now her profile appears as Bernadette P. Jordan, with no reference in the title to Sr. Catherine Marie. I first tried Sr. Catherine Marie as preferred name, but then that is how her profile appears, without mentioning Bernadette Jordan. The biography should be fleshed out, if possible regarding her entry into her vocation. If consensus decides a different approach, I would be happy to correct the names.
As an aside, the My Heritage sources are way too long. The bio should be rewritten, and if possible, replace the sources with familysearch sources.
