Many thanks for sharing this painting. I researched the Campania extensively for my book “Shipwrecks of the Cunard Line” but I don’t recall seeing it before. So I am intrigued to learn more about it and assist in any way. So far I have not been able to find any record of Captain Rowles being involved in any rescue involving a Cunard vessel. However, it does seem a high probability that your ancestor was Captain Thomas Rowles of the Jane Bacon. This was a Liverpool registered iron-screw steamer operating coastal trade to UK ports. The Jane Bacon was involved in a collision with the Lara in the Bristol channel on 25-jan-1882, then another collision with the Lord Marmion off Swansea. A third collision on 23-dec-1887 off Crosby with the Lombardy resulted in the loss of the Jane Bacon.
