I really think so too. I think it would require some real effort to come up with a surname that doesn't exist in the US. I don't think it was random at all. Finding Bilemy as a name outside the US could very well be a clue. I still think about where people disappear to and feel there may be some religious or spiritual background or connection with Mostly Harmless... so of course missionary work comes to mind. A person can go almost anywhere in the world doing missionary work. It seems that it would require proper IDs, passports and vetting these days. Is there anyone here that grew up with a family that traveled doing missionary work? There are many organizations online that assist people wishing to get started. It appears you don't have to do this directly through a church.
