Ah, think I figured out the problem - spelling.
The ship's name was actually Blanche CurrIE.
The only reference to a Blanche CurrY - a newspaper entry (that I'm pretty sure got the spelling wrong) - is actually on this web site
qnd repeated (with slightly different wording) at rootsweb.ancestry. See next. Is this where you got the spelling of the ship’s name?
This web site: Feb. 5 - "Blanche Curry" passed Cape Race. Not since heard of.
Rootsweb site: February 5, 1914 - SCHOONER MISSING "Blanche Curry" passed Cape Race. Not since heard of.
Found the correct spelling by following a link that is actually provided on this forum (thank you Wanda)! Go to Genealogy Hints & Tips / On-Line NL Crew Names List to access the link. It goes to the Maritime History Archive entry for A.H. Murray and Company - under section 6.03 Bills of sale, 1925-1942 you will found the Blanche Currie among the vessels listed.
If you note the date range 19*25* to 1942, it implies the ship didn’t sink in 1914.
That being said, the left side BOTTOM link -- NL Crew Members -- would seem the best way to check because your relative’s name should be listed.
A further potential option is [http://www.] nmm.ac.uk/researchers/library/research-guides/the-merchant-navy/research-guide-c6-the-merchant-navy-the-mercantile-navy-list. They are Microfiche files so there may be a fee attached to having someone check, but it might provide more information about your relative.
Hope you pop back to the forum at some point and see this info. Then again, you may already have found it – if so would you post to advise?
Cheers
