Buying a Christmas gift for brothers-in-law or great aunts can be a frustrating experience. You don't know what they want, and they are not likely to remember for more than a moment what you give.

One person recently e-mailed me about his plans this year to give brother-in-law gift money to armed services charities: "We want to help the families of those who have contributed to America at a level that most of us don't. . . . Could you suggest worthwhile organizations and aid functions?"

That's a wonderful idea. Here are three fine organizations:

The Injured Marine Semper Fi Fund (semperfifund.org) provides assistance to Marines and their families wounded in the war and undergoing rehabilitation.

Soldiers' Angels (soldiersangels.com) matches civilians with military members serving in the war zone and provides assistance (such as voice-activated technology to soldiers, sailors, airmen, and Marines who have lost the use of their hands).

The United Warrior Survivors Foundation (frogfriends.com) provides assistance to the families of special operations personnel from all branches killed in combat.

There are many other fine organizations as well. Cards can be sent to relatives noting the donations made in their names. These gifts would be remembered and honored.
