1877 Plat map with WR (Riley) Blythe farm easily found west of Albany/Ada. Note current Brashears Rd is clearly identified on plat map as is West 73rd and west 74th St. Albany Rd is also clearly marked and matches.

I still have not pinpointed the church or mine. DNR does not list an abandon mine in this area though there are several contemporary references to its existence.
