LW1 - You sound like a good person, and your siblings and your community are lucky to have you.

I hope that if a check is returned to you or donated, that you won't be sad or offended. It has nothing to do with whether your sibling loves you, and it's not a rejection of you as a person. Some people feel weird about receiving money, and a lot of people dream of being self-made. Even if they don't accept your gift, they may still appreciate the sentiment.

Another option is perhaps you can ask the siblings what they'd prefer? One may want cash toward a mortgage. Another may want a contribution to a child's college fund. Another may have no needs at all, and then you can ask if they have a charity that's dear to them.
