Help reading an old map (1874, US, Illinois)

by goethean

In this map (original here), above the word "Lisle", is a property marked as "Schrodie Est." I am wondering if this is likely to be the owner's name, or is 'Est.' is an abbreviation for something? If so, what? Thanks!

Est. for Estate. Yes, it's an old plat map of the township, so that was the owner of that 140 acre parcel.
