I am saying Kaddish for an aunt with no one to say Kaddish for her. I am often asked to say kaddish for others who are late for a minyan or who are otherwise unable to say it. May one say Kaddish and have more than 1 person in mind? Please can you let me know the Mekorot for your answer. Thank you so much!
This is an old machlokes; Rav moshe holds that one cannot; Gesher Hachayim holds that one may.
