The Sheridan plat map: start here
For land around Lafayette, look for the plat book reference on the parcel record; use it to request a copy.
The free map to start with
Begin with the ORMAP statewide tax lot viewer; it covers each tax parcel around Dayton and McMinnville. For a home near Carlton, type a street address, an owner's name or a parcel number, then pick the result to center the map on it. For property near Yamhill, a pop-up or side panel typically gives the owner of record, acreage on the tax roll, the parcel number and sometimes recent sales.
Backing up the map with records
The map is an index, not the title: recorded deeds, subdivision plats and easements covering ground around Amity sit with the County Clerk. Inherited tracts near Carlton can trace back through several deeds, so a title company can sort it out if money is changing hands.
City limits and county records
Sheridan lies within Yamhill County, Oregon, and the county assessor maps its lots. If you're looking near Amity, the municipality handles things like zoning, permits and utilities within town limits, and the county still keeps the parcel and deed records. Lots just outside the town limits near McMinnville generally falls under county rules rather than the town's.
Two different maps
When the two disagree for a lot near Carlton, go with the plat and a surveyor's work.
Details on the Sheridan plat map

What the map can't tell you
