Needing help.... in Gonzales, Gonzales County, Texas

I apologize in advance if I am not supposed to post a question of this sort but desperately looking for some guidance.
In the spring 2004 or 2005 we purchased a German Shorthair Pointer puppy from a litter of 12 from wonderfully kind older gentleman. All we can remember is that he lived out in the country there in Gonzales and had bred pointers for many years.
I am not sure of the gentlemens name we bought our sweet Gus from...even if is possibly still alive but if anyone has any information as to this mans name or maybe someone knows of his family members even, that might possibly be able to help my family find our dear Gus’s family lineage.
We lost our sweet boy Gus today after a very hard battle of being ill.
