When my mother's time comes, she wants to be cremated and buried with my father. He was not cremated, but buried there in 1974. Can we bury her ashes there in the two plots where my dad is buried?

Yes I can. My infant brother was buried 1st, 1956. Then my father, 1967. Then my mother, 2015. The office told me that I could put one cremation in this plot. My mother stated that the section they were buried in is only for two people, they don't count the infant. So if one of my sister want to they can go in their they can.

I do believe you can call one of the counselors at the office they will be happy to give you a hand
