The Name Game-Naming a child after a non-Frum family member

According to Mori V’Rabi Harav Hagaon Reb Shlomo Miller shlita: Naming a child after a non-Frum family member is acceptable & at times even recommended. The main reason we name after an individual who passed away is to honour him or his living relative. It is usually  done as Hakaras Hatov we have for them. Hakaras Hatov overrules all the reasons of not naming after a non-Frum person. We find Bnei Yisroel as a Hakaros Hatov named their children after Alexander the Goy. ------------------------------------------------------------------------------------------------------------- The Zohar writes, In all the names of the שבטי יה, there are no Ches ח or Tes ט .
