Point only works for Dustin, Lucas
1975 Indiana, Erica was #63
1972 Indiana, Michael was #1, William was #9
1968 IN Robin was #44, Nancy was #47
1967 Steven was #15
In 1966, Indiana, Jane was #72, falls out of top 100 after that.
The dataset stops in 1960, so I don't know when Jane fell out of top 100 in CA, before 1960 anyway.
My original point is substantially proven; Jane was quite old fashioned name for a 14-15yo kid in 1986 in California to have. I knew. I was there.
I am surprised about Janice being in top 100 so much. I only know one for sure, my aunt, born 1940s! Maybe Jan's are mostly Janice, I've known many, born 1940s.
