I presume you are referring to this URL: http://www.armed-guard.com/dork2.html where, on the ninth page down, your father-in-law's name appears as "WACDTEL, LOUIS."
This particular URL is an image of an original military communication reporting the loss of USAT DORCHESTER. That is to say, the error appears in the original document. As such, I regret to say that I am unable to edit it.
Sincerely yours,
Ron Carlson, Webmaster Armed Guard / Merchant Marine website www.armed-guard.com
