Yesterday my family buried my great aunt by marriage. She was 91 when she passed away. She and my great uncle (possibly 92 or 93 years old) celebrated 75 years of marriage on July 29, 2004. Both had lived in nursing home the past few years afflicted with Alzheimers.
When they married, my grandmother was on her 8th month in my great grandmother's uterus. She is the baby of the family.
