I left him as a “question mark?” because there is some overlap, but it might also be some errors in the databases, where they mixed the two (”K” and “R”) up. I’ll go back when I get a chance and try to clear it up.
You’ve probably seen by now that his adoptive father was named Donald D. Hall and his mother Carol J. Hall and they haven’t seen him in several years.
I don’t think his original name was Hall, either - as in a birth father being a relative - because they claimed to have found out about him in the newspaper before putting in to try to adopt him.
IF so, there’s also the age given as 51. So more is mixed up than a K and R. It leaves me rather confused.
