I used "Olive" in GEM and NH, so her initials would be LOL.
But that's just me. I like funny initials. My daughter's is LAF and I won't tell you my son's, but they spell out my maiden name. As I said, I'm silly that way.
Since all her friends from high school called her LoLo, I could easily see L&C's Lois having a middle name that started with an "O".
