He is buried at Arlington:http://www.findagrave.com/cgi-bin/fg.cgi?page=gr&GSln=al...
This indicates he was born in North Carolina. They "might" have been married for a short period of time. He was in the Navy, which indicates a possible duty station at San Diego.
The date of her mother's obit is VERY IMPORTANT. That would give a time-frame for this potential marriage between the two.
I would contact the children of the KNOWN Lorna.
