OK - so I have the correct solution then. Happy to read 35d as a 4 letter real word with a space in it.
I was puzzed about how the first 2 hiders were linked and spent some time trying to link hiders to seekers - without success obviously.
I also wondered if the first 2 hiders were famous for hiding like the "third" one. No joy there either.
I actually spent more time with Google after completing the puzzle than while doing it.
There are at least 12 real given names "hidden" in the grid but only 2 are linked by "is the" and "of" to the relationship. I guess it is not important as the first two hiders do not need highlighting.
