I am so sorry to have read of your loss. Please accept my sincere condolences. Something that I have personally found to be of great comfort is what the Bible says at John 5:28, 29 as well as Revelation 21:4. These verses show us that soon God is going to bring about a resurrection of our loved ones as well as do away with all causes we have for suffering including sickness and death. Knowing this has always comforted me and it is my sincere hope that these thoughts comfort your family as well. Again I am so sorry for your loss.
