My family at first. Though I already had faith as you read yourself. Overtime things clicked into place like puzzle pieces. Making sense or being proven as true by life itself.
I think that faith within the family is very helpful for holding people together. Although my family was so totally dysfunctional, I can't imagine faith would have helped. My mother liked sociopaths and the overly "religious" ones are the stuff of nightmares.
Generally Buddhism has proven itself to me. Culturally it is like any other religion with people worshipping Buddha... but on a private level it is very scientific and clicks quite well. Meditation is very powerful and I would feel highly unsettled without it at this point. I don't know if Buddha existed (likely in some person or an amalgam of people). I simply focus on the lessons it teaches as I do with things I find in other religions.
For me, Buddhism is simply logical.
