ISO: Two Author's Full Names

Does anyone know the first names of R.L. Stine and/or J. K. Rowling? - Jinx

I had no idea, but I came across this tool, and I came up with them by typing in [j.k. rowling full name] and [r.l. stine full name]. That tool works great, but be careful–there’s a lot of misinformation out there.

JK Rowling is Joanna Kathleen, more commonly known as Jo.

I think I used to know RL Stine’s, but I seem to have forgotten it.

R.L. Stine - Robert Lawrence Stine (according to the Literature Resource Center database available to me here at work)
