Who is there going to be who can identify them. It could only be done from photos.
Do we have a list of those who lost their lives on the ship? DNA could eliminate some—other records like height and age could eliminate more. The ones that are left could be our guys. I am glad they were found and will be given a decent burial after these many years. How many more rest in the hull?
I wonder if they have studied the ancestry sites on the net. They can have old pictures and details in them.
