In searching for Packard heraldry, I have come across two different ones. One has a blue background and the other is a red background. I have not been able to put individuals names to either of the flags, so I'm assuming that they are for two seperate people. Does that make sense or am I barking up the wrong tree, sorry no pun intended.
Both flags are similar but not exact, that is why I think they might be for two different people.
Any help is appreciated
