I am very sory for your loss, but heir is no single memorial with the names of the sailors, lost in the Atlantic. So many people have been lost there, that it would just be impossible to list them all in one memorial. Unless that memorial was a building, and inside it books of all those lost. If you were to go to the UK, and visit any town, in that town, would be a war memorial, that you can find, if you look for it. On that memorial, is the names of the fallen, for two world wars, but only the fallen, from that town, or village. If you go to a small village, the memorial will have a few dozen names, if you go to a big city, their will be numerous memorials at different parts of that city, listing the names of the fallen, from that part of the city, in two world wars. If you look at uk casualties, they lost almost 400,000 military personnel in the second world war, the first war, they lost over 900,000, now think of trying to fit all those names onto the one memorial. But it does exist. In Edinburgh Castle, their is a building, with every name of every British soldier that died in those two wars, the names are in books that are at places round the room, listed as regiments, so to look up a name, you have to know the regiment, and the date the person was killed.
A large number of the UK dead from both wars, died in the Atlantic, so other than a name in a monument, and a name in a book, their is nothing.
I think thier is a monument in newfoundland, with the names of Newfoundland fishermen who died out at sea, but as of yet, yachties have not organised to build a monument for sailors lost at sea, The obviouse answer would be for every marina, to have a memorial, with each sailor who sailed out, and never returned homes name on it, but, it would probably be bad for business, so they wont do it.
I went to home depot in joplin last week (it just re opened after the tornado tore it down) they had a paque up for the people who died there, seven people died in the store during the may 22nd tornado, they put up a simple plaque, with no names on it. Which is wrong if you ask me, it kind of de humanises it, they should have put the names of the dead on the paque, rather than just say, "for those who died"
