Sorry to hear of your loss. We went through that in 1970 when my dad, father-in-law and nephew died. My nephew was killed in Nam one day before his 23 birthday. He's buried at Arlington.
My wife's mom lived another 14 years and my mom another 24 years. She was the 2nd oldest of 13 children. Her baby sister just turned 85. My wife's oldest sister will turn 95 in Dec. I think she will out live her son as he's in poor health. Hal
