Honestly, I've received quite a few- all by one lady.
The first time I actually got one from her was probably a year and a half ago, and she left a message on my voicemail starting "Hello, Sister Rosemary..."
She goes on about wanting to catch up with her and just saying hello and everything. I seriously thought someone was making a crank call and just decided to leave it on a voicemail when I didn't answer. It was funny and I showed it to a few people, but I didn't think about calling this person back or anything because I figured it was a one-time deal.

About a few months later I get another call, from the same lady! It kills me because I can't remember her name. Sister... something. ANYWAY! She was calling for Sister Rosemary again! At this point I realized it wasn't a crank caller anymore, but I was in poor reception when she called so it went straight to voicemail. It was funny because she was once again saying how she wanted to catch up with her. I didn't call her back this time either, and I probably should have.

Finally, a few months after that, I managed to catch this lady's call. I had explained to her that I wasn't Sister Rosemary and I haven't gotten another call from her to date (:
She probably just mixed up the phone number when she was dialing it a few times, because this number has been apart of our cell plan for 6+ years. Hahah. I just don't know...
