Understanding mapping units in subdivisions in 9N 11W and 9N 12W

We have rights in 9N 11W and 9N 12W. These are inherited and shared with other family members. The legal description clearly spells out quadrants within the sections clearly, however part of the holdings are in Lots that were possibly part of a subdivision of the property. I am not sure how to locate these parcels. Does anyone have a direction I can go to view subdivision maps around Albert and Oney?

My mother and other family members were raised in Oney in the late 20's-early 30's which is where these rights began.
