My bad! I should have trusted your spelling abilities.

Vineyards at Marsh Creek might apply to the broader neighborhood; Trinity at the Vineyards appears to be the designation for Club Los Meganos’ +55 residential complex (a Shea Homes development project).
Perhaps wineries are contractually bound to use the “Trinity” name on their labels to add prestige to the housing community. Honestly, I use the names interchangeably.
