My interest is in William Caldwell as I have this but nothing about his mariner life, or his death.

*Sandra* (reply 144 on the very long thread) discovered news cuttings including the wedding in 1900 - The South Bend Tribune, Indiana, Wed, 27 Jun 1900 Page 3 reported that county auditor John Brown returned from his sister's wedding in Quebec; Mr Caldwell was first mate on the Oceanic of the Dominion Line, and Mr and Mrs Caldwell were sailing to England today.
Also she found in 1904 June 13 South Bend Tribune: Court cases, including Mrs Jeanette Isabel Caldwell granted a divorce from William Caldwell in chambers on a charge of lack of support. The plaintiff is a member of the firm Caldwell & Anderson.
I've looked at Ships List website, where it states there were two different Oceanic ships. One built 1870 for the White Star Line and scrapped 1896 in Belfast, and one built 1899 for the White Star Line, with the maiden voyage 6/9/1899 Liverpool to Queenstown (now Cobh), Ireland and Boston, continuing with this route until 1907. The Ships List also has info on the different sales, ownerships and combination of lines in this era, and it seems that the Dominion Line name continued to be used, but their fleet list doesn't show Oceanic there. There is a route for one of the lines Liverpool-Queenstown-Quebec though.
I wonder now if I've assumed the happy couple sailed on the Oceanic? He was first mate on it, but doesn't mean they travelled on it back to England. Perhaps he had a perk of discounted travel, or not, but could have sailed on any boat.
I have been looking unsuccessfully for him as crew on any ship at all, and cannot find his death, but Caldwell is a common surname in the area of his birth. Of course being a mariner he could have died at sea or in a port abroad.
Can any of you find him anywhere please? To save you wading through the very long thread, there is little to be gained by searching for his wife. She was at her half-brother's house in Birkenhead, England in the 1901 census, with no William (at sea or already separated?).
Thanks for reading.
