Need help from DU vets regarding charities

I had great help from someone back in NC selling my old home. He was able to arrange the estate sale and sale of the house.
I could not go back due to medical problems. He also sent packed and shipped some items, including my dad’s old army trunk which contained items of great sentimental value.

I was billed and paid for all this, except for the shipping of the trunk. Jack said that although he has never served, he was doing that in order to honor a veteran.

Well, this veteran’s daughter would like to do something to reciprocate that kindness. So I thought I’d make a donation in Jack’s name to a charity that helps veterans. I’ve looked on the internet, but can’t be sure which are legit. So I’m asking the ever helpful DUers.

My dad served in the army in Panama for a few years, then came back, met mom and got married. Then Pearl Harbor occurred and he knew he had to go, but because of his previous service he was not in combat. He was a machinist mate in the Seabees, stationed in New Caledonia.

So that’s my story. If you have any suggestions about organizations that help either service, I would be most grateful.

Thank you.
