No Greg Brock is not related to David Brock, who was an orphan adopted by the Brock family in Texas. David has a sister, but I’m not sure whether or not she is a Brock by bloodline or not. I doubt it. David’s well-to-do father died back in the 90s if I recall correctly.
Thanks for your time and the info.
I’m always surprised when a name pops up from a long-timer that I don’t recall ever having seen before.
I’ll look forward to your posts in the days ahead...they might be some busy days!
