According to the annual volumes of Lloyd's Register of Shipping for 1857/58 through 1865/66, the British ship THAMES CITY was built under Lloyd's Register of Shipping Special Survey at Sunderland, in 1856. 557 tons; 142.0 x 29.5 x 17.5 feet (length x beam x depth of hold). Her master was J. Glover, she was owned by "R'nthwte" (a name I cannot expand), and registered in Sunderland. Only the annual volumes of Lloyd's Register volumes for 1857/58 and 1858/59 give a destined voyage; in both cases, this is to India. The entry for the THAMES CITY in the annual volume of Lloyd's Register for 1865/66 is posted "wrecked". I cannot find any reference to this wreck in Palmer's Index to the Times (London), but the ship was not an important one.

The bremen bark THEONE was built at Bremerhaven by the shipwright Johann Carl Tecklenborg for the Bremen firm of C. L. Brauer & Sohn, and was launched on 24 June 1864. 589 Lasten / 883 net register tons; 150 Bremer Fuß 4 Zoll x 30 Fuß 2 Zoll / 43,50 x 8,73 meters (length x beam).

The THEONE had a short career. The New York Herald for 7 December 1869 prints the following notice of her loss:

Rotterdam, December 6 - Bark THEONE (N[orth] G[erman]), Captain Hellmers, which arrived from Philadelphia Nov. 16, and having on board 260 bbls petroleum, has been burned in the harbor, (From books of Pine Street News Room.)

M. Hauschild, [1994]), p. 158, no. 131; New York Herald, 7 December 1869, p. 7d-e. The collections of the Deutsches Schiffahrtsmuseum, Bremerhaven, include a half-model, prepared by Dr. Georg Claußen, Betriebsdirektor at Tecklenborg, that was originally purported to be of the THEONE (a copy of this model, prepared in 1913 by C. Battré, is in the Focke-Museum, Bremen, Inv.-Nr. B.889, and is illustrated in Lachs, loc. cit.). However, recent research at the Schiffahrtsmuseum suggests that it is in fact a model of the bark COLUMBIA, which was built by Tecklenborg in 1861 for the Bremen firm of D. H. Wätjen & Co.
