"Tansey Point" is mentioned in the 1862 U.S. Coast Pilot:

"... Young's bay lies between the eastern part of the Clatsop beach (called Tansey Point) and Point George. Into it empty Young's river, discovered, examined, and named by Broughton; Lewis and Clarke's river, examined by them in 1805; and one or two small streams or sloughs. ..."

The Clatsop Beach of the mid 1860s was the sandy beach around Point Adams.

The 1869 U.S. Coast Pilot mentions "Tansey Point" as the location of "Buoy No.4" of the Columbia River.

"... No.4. -- Iron buoy, black, marking north side of Tansey Point, in fifteen feet of water. Last buoy bears west by north half north, one and three-fourths miles; Scarborough Hill, north-northwest, three-fourths mile; Tansey Point, south by west, three-fourths mile.

From the 1889 U.S. Coast Pilot:

"... Tansy Point. -- This is the low point on the south side of the river a little over two miles east by south half south (E. by S. 1/2 S.) from Fort Stevens. It is low, marked by small sand dunes with low marshy ground behind it, through which drain Tansy and Alder Creeks. There is a broad low-water sand beach in front of the point, and the three-fathom curve lies three hundred and forty yards outside the shore-line. A black buoy marks the north side of the channel abreast of Tansy Point, and there is deep water and a strong current in the channel-way between the buoy and the point.

At the mouth of Tansy Creek, southeastward of the point, there is a large cannery and quite a settlement along the shore. ..."

Tansy Point was mentioned in the "Spokesman-Review", November 22, 1895.

"... In the early part of 1843, A. Trask, W.T. Perry and W.W. Raymond came to Clatsop plains ... . W.W. Raymond settled at "Tansy point", now the embryo city of Flavel. Raymond was Indian agent there, and in 1852 claimed to have over 600 Indians under his care. ..."
