In Petros http://www.nautilia.gr/forum/showthr...998#post178998 I added the following which I am revising now by adding additional information.
Elvira was one of the two daughters of G . Potamianos! The Greek passenger ship Elvira was built as the yacht Greta ("after the small stream which runs through the Halskill Estate") by Scott & Co of Greenock for the shipyards' owner J. Scott in 1898 (who said the old man Potamianos did not have taste?). The June 1, 1892 Marine Engineer says "The builders will supply triple-expansion engines of 300 HP"... That would make her rather powerful. She was bought by G Potamianos in 1927. She had 372 tons with a length of 50.3 m and width of 6.9 m. She was scuttled on April 23, 1941
Here is a photo of Elvira when she was Greta from the book Two centuries of Shipbuilding by the Scotts at Greenock.

Also here is a typical Elvira schedule of June 1934
