Thank you for the above links, which make finding profiles to work on so much easier. I do hope this thread, or a new one gets posted periodically to remind us, about this task. I tend to bounce all over the place, working on the wheel that is squeaking the loudest, at the moment.
Found several, some attempts, revealed no LNAB, but did get sources added to their profiles (also to hubbies), and although couldn't find a LNAB for one lonely profile, did get her reconnected to her family, after she was thrown overboard in the gedcom upload. A few were like winning the lottery, when the source search for hubby, had their marriage cert. at top of list. And WOW one of those marriage certs had so much info - the full page of questions, where like an app for high security job.
