So as we all found out Agent Triplett is the grandson of a howling commando. Seeing as the only proof that we have is that the only African American in the howling commandos to fight Hydra was Gabe Jones (though there is no proof that he was the only african american) but yeah, That his is grandfather and I find that amazingly cool.

Gabe Jones: In 1943, Jones was captured sa pamamagitan ng HYDRA and placed in a cell with other allied prisoners. When Captain America single-handedly assaulted the facility in which he was prisoner, Jones, along with his companions, broke free and wreaked havoc on the HYDRA soldiers and the base, coming back to US military base immediately after.

Shortly after their breakout, Jones and his comrades were invited to sumali a special elite squadron, led sa pamamagitan ng Rogers himself. Jones, after a brief conversation in French with Jacques Dernier, happily accepted. Along with the other Howlers, Jones took part of every assault against HYDRA, and it was Jones that took HYDRA scientist Arnim Zola into custody. Jones was present at the final assault against HYDRA at Johann Schmidt's fortress, and was one of the last people to speak with Captain America before he was Nawawala to the ice.
