Julie,
for Lois middle name, I also remember this story where she's refered to as Lois Joanne Lane.
As b-day is concerned, the book "Lois & Clark: une série postféministe" (LCTNAOS: a postfeminist tv show) only gives a birth year for Lois: 1967.
As she's a Libra in the serie, you can pick up a date between sept, 24th and oct, 23rd...
Carole (who thinks it would be really funny if Lois B-day was oct, 16th)
