Help!? White habit Immaculate Conception Sr. in Rome?

[Lisel5Roses]

I met an Italian sister on the Roman metro on the Red line, between the Spagna, Barberini or Republica stops, and used Google Translate to have a brief conversation but she had to exit quickly in the crowd and never managed to give me her number. We shouted we'd find each other on Facebook but I'm having trouble. Her habit and veil are all white, very similar to the Salesians (which in fact was why I approached her in the 1st place), similar to these cuts. https://cmswr.org/community/daughters-of-mary-help-of-christians-salesian-sisters-western-province/ 

Anyone have an idea as to which Rome order she is in? In broken English, we made out that her "congregatio" is titled something "....immaculate conception".

I have her first name and last initial, that's it. I'd be so so very grateful for any help - it would mean a lot!

It's not these: http://www.sorelledellimmacolata.org/en/gallery Her veil was white and not so low and tight on the forehead, I don't know about a cross as she had on a cream colored thick sweater.
