Context: The second RMS "Laconia" was a Cunard ocean liner, built by Swan, Hunter & Wigham Richardson as a successor of the 1911-1917 "Laconia".  The new ship was launched on 9 April 1921, and made her maiden voyage on 25 May 1922 from Southampton to New York City.  At the outbreak of World War II she was converted into an Armed Merchant Cruiser, and subsequently a troopship.  Like her predecessor, sunk during the First World War, this "Laconia" was also destroyed by a German submarine.  Some estimates of the death toll have suggested that over 1,649 people were killed when the "Laconia" sank.  The U-boat commander Werner Hartenstein then staged a dramatic effort to rescue the passengers and the crew of "Laconia", which involved additional German U-boats and became known as the Laconia incident. RMS "Laconia" was a Cunard ocean liner built by Swan Hunter & Wigham Richardson, launched on 27 July 1911, delivered to the Cunard Line on 12 December 1911, and began service on 20 January 1912.  She was the first Cunard ship of that name. The RMS "Franconia" was an ocean liner operated by the Cunard Line.  She was launched on 23 July 1910 at the Swan, Hunter & Wigham Richardson shipyard in Newcastle upon Tyne. RMS "Aquitania" was a Cunard Line ocean liner designed by Leonard Peskett and built by John Brown & Company in Clydebank, Scotland.  She was launched on 21 April 1913 and sailed on her maiden voyage to New York on 30 May 1914.  "Aquitania" was the third in Cunard Line's "grand trio" of express liners, preceded by RMS "Mauretania" and  , and was the last surviving four-funnelled ocean liner.  Widely considered one of the most attractive ships of her time, "Aquitania" earned the nickname "Ship Beautiful". RMS "Mauretania" was an ocean liner designed by Leonard Peskett and built by Swan, Hunter & Wigham Richardson for the British Cunard Line, and launched on the afternoon of 20 September 1906.  She was the world's largest ship until the completion of  in 1911 as well as the fastest until "Bremen" 's maiden voyage in 1929.  "Mauretania" became a favourite among her passengers.  After capturing the Eastbound Blue Riband on her maiden return voyage in December 1907, she claimed the Westbound Blue Riband for the fastest transatlantic crossing during her 1909 season.  "Mauretania" would hold both speed records for twenty years. Johanna Veenstra (1894–1933) was the first missionary of the Christian Reformed Church (CRC) to go to Nigeria.  She was born on Thursday, April 19, 1894, on Hopper Street in Paterson, New Jersey.  Her parents were William Veenstra, later a Christian Reformed pastor, and Cornelia Anna De Hoop.  In 1915 she was challenged by Karl Kumm of the Sudan United Mission (SUM) to be a missionary in Africa.  On October 2, 1919, she left New York City on the "Mauretania" for England; on December 31, 1919, she took another ship to Africa, arriving in Lagos in January 1920.  In February 1921, she arrived at her station in Lupwe, which is near Takum, now in Taraba State.  Two years later Johanna Veenstra assumed leadership of the work in Lupwe.  She was engaged primarily in medical work and in preaching.  During her ministry in Lupwe, a number of people especially of the Kuteb people became Christian and also became more educated.  The roots of the Christian Reformed Church of Nigeria (CRCN) and the Reform Church of Christ in Nigeria (RCCN) Headquarters in Takum, Taraba State Nigeria lay in part in the work of Johanna Veenstra. Leonard Peskett, OBE (1861 – 1924) was the Cunard Line's Senior naval architect and Designer and the designer of the companies ocean liners RMS Mauretania, RMS Lusitania, RMS Aquitania, and the RMS Carmania.
