Familiar with Edinburg, TX?

Seeing if there some HAMB help available on this...

I own a '62 Grand Prix that was sold new in Edinburg, TX to what I think is Holcomb-Dorris Motors.

Is that the correct name of the dealership?

Anyone have early pics of the place?

Anyone here have relatives that worked there in the early '60s?

...Lotta what-ifs, but I believe there is a HAMBer (or several) who can help.

Thanx in advance.
