Louis Kinsella appears on the Ellis Island Records as a "Stowaway" on the BALTIC in 1909, along with a second person, whom if I remember correctly was a "Newspaper Vendor" or similar.LK gave his Father's Name and Address for his "Next of Kin", although already married etc.Being "Stowaways" they do not appear on the Ship's Manifest for Departures, submitted to the Board of Trade.
Louis also was deported from Boston in 1905 on the RMS Arabic, as a stowaway. He was also listed as "deserting" the SS Maplemore in 1899. Also in 1907 he was listed as "deserting" the RMS Majestic. He is shown on the crew list for the SS Pinemore in 1899 and the SS Rowamore in 1901. His wages were £4 for working as a "trimmer". In 1902 he was listed as crew on the "Hanoverian".
Louis Kinsella was married to my 2nd cousin 3x removed Rose Anne Clarke, the Clarke family originated from Co Meath in Ireland. Findmypast and Ancestry websites have lots of Titanic documents connected to Louis Kinsella.
