Several years ago on a trip to Missouri, we stopped in the town where my mother-in-law was born. The local library didn't really have any genealogical materials, but they did have old high school yearbooks. I decided to look through them for a few of the older siblings who graduated from school there before the family moved to Moline, Illinois. I was really just hoping to get a few pictures.
Imagine my surprise when in the "biography" of one of the older brothers it stated he attended part of his junior year in a Chicago area high school. I had never thought to ask this question might never have if it had not been for the yearbook.
Leads turn up in the most unusual of places.
