I cannot see how it can be any more specific. I said 'Stated on BOTH Wills' so that there can be no misunderstanding in either, and 'to my Son' is merely an example, and was quoting the OP. Of course his son's name, DoB & current address should be added, the same for his GF. You seem to have mis-read what I posted.
And if there is any problem deciding what I mean in my Wills, they can come and talk to me to clarify things. 555
