Permission to seal my cousin to his parents
In 2017 my Great Uncle Scottie (my grandma's youngest brother, born in 1920) and Great Aunt Melba gave me permission in person to do their son's (their only child who never married and who died in Vietnam in 1971) temple ordinances (they were Baptist). I was able to complete all temple ordinances except for sealing my cousin to his parents. Since they were both living, I thought I would need to wait until they passed. (I found out differently today from family search mobile help).
They have both passed and I have completed all temple ordinances for my great aunt and uncle except for sealing my cousin to them. I was told I would have to wait 110 years -- my cousin Greg was born in 1947. I may not make it that long (2057); I was born in 1960.
What can I do?
