I think I found why Christina Smith Laurean has a different maiden name than one would have expected. She’s apparently not a Shifflet by birth. http://answers.yahoo.com/question/index?qid=20080115100623AA0VQ22
Yes, I believe her mother remarried. I think her original name is Christina Smith. By the way, did you check out my post, 2076? Are you able to blow up/darken that sign to see more of what it says?
