I found this several days ago when "Raymond" was first mentioned, I was going to research more, then I forgot about it.
You will see in the picture below, Julie is "related" to a "Raym" (last line, last word). I think it's safe to say this is "Raymond". I'm not curious enough to pay the $1.99 to find out. I'm sure with enough research and I could find it for free.
I'm going to go out on a limb and say the real "Raymond" (Not the pet name of Dan Chen) belongs to Jami's brother/half brother or is possibly Julie's new husband. If someone wanted to research this further, they can likely piece it together.
