Street Names Now and Then

I'm trying to keep track of what the various roads around here used to be called. And by "used to" I mean between 1900 and 1930, roughly, although State Road 51 was known as Ainsworth Road as recently as the 1950s.

Ainsworth Road (east of S.R. 51)	Chester road
Ainsworth Road (west of S.R. 51)	Ainsworth-Merrillville road
73rd Avenue, Lincoln Highway, County Road 330	Joliet road, Road #30
