Jerry, thank you for your input as it was a reminder for me to be methodical about the problem. Sussed it. This time in my large database I put in my Test citation against the individual's name fact, which is how I had done it before. The citation that I was having trouble transferring was against the individual's parents fact. So niether citation in the lower section against any event facts. When I moved the individual into the small database and then CHECKED to see what had come over, The Test citation had but the other hadn't. D'oh! Of course, since I was just tranferring the individual the parent-associated citations get left behind. When I copied that parent citation and copied it into the individual's name sources, it copied over just find and then all I had to do was the merge than copy that citation and paste it into the parent fact sources and then delete it from the name fact. Just need to compare the databases now for the people I had to more from the large one to the small one as individuals or jsut with their spouse(s) and make sure no other parent source citations got left behind.
Thanks, community. I can depend on eventually finding an answer here.
