A few quotes from the Rabbi on 'Tzedakah and Healing'
in which he teaches to give half to his relatives and half to all the other poor.
One who has poor relatives can ostensibly divide the charity he is in the habit of giving: half to those closest to him and half to all the other poor, as indicated in Tractate Pe'ah, Mishna 6, where we learn that "he may retain half and give half". Should one have a minimal amount – one hands it to them and they divide it amongst themselves. See Rabbi David ben Zimra's published Responsa, paragraph 147
