From "History of Erie county, Pennsylvania"; Samuel P Bates,
1884:
The true boundary line between Erie and Crawford Counties was
long a subject of dispute. To settle the question, the Legislature
passed an act at the session of 1849-50, providing for three
Commissioners to run a new line, who were given full power to act,
and whose decision should be final.
In 1850, Humphrey A. Hills, then of Albion, was appointed
Commissioner for Erie County; Aidrew Ryan was appointed for
Crawford, and they two named H. P. Kinnear, of Warren, as the third
member. Wilson King was chosen Surveyor on the part of Erie, and
Mr. Jagger on that of Crawford, but David Wilson, as deputy for Mr.
King, did most of the work.
The party had some difficulty in finding a starting point, but
after this was agreed upon, it only took about six weeks to
complete their task. A perfectly straight line was run from east
to west, and marked by stones set two miles apart. The
Commission added a long, narrow strip of territory to Erie County,
which is usually outlined upon the county and township
maps.
A number of persons found themselves in Erie who had supposed they
were citizens of Crawford, and a less number in Crawford who had
imagined they belonged to Erie.
A Mr. Reeder, of Washington Township, had been so anxious to be a
resident of Erie County, that he left his original house and moved
into a new one which he supposed to be at a safe distance from the
boundary. When the final line was run, the second building was
found to be in Crawford, and he was compelled to erect a third one
in order to secure the desired residence.
See that part about the stones? If you stumble across any of these
stones, let me know!
