I am one of the coordinators of the New Orleans rootsweb site. I was just transcribing some coroner's records for our site and came across a Thoams Los who died in New Orleans in April 1863. The records says he was 74 years old and a native of Manilla. Can anyone connect with him? Let me know. I have a little more info - not much, but I can point you in some directions you might look for more.
He might not have been born in Manilla - he may have worked as a seaman and was most recetnly from Manilla.
