Burial of Cremated Ashes for Mom and Dad

Hello from Janice Linsky, Joanne Saunders and our brother Robert Kent Sthuhlmann. I’m not very comfortable with asking this request. Both my parents were cremated. Dad John Dudas in 1990 and Mom Phyllis/Betty Chubbuck in 2009. I’ve kept them in my possessions together since their time of passing. My brother and sister and myself have been trying to come to the best possible compromise we are all in our 60’s, 70’s, and 80’s and we would like to be there together when we they are placed and the 3 of us can be there. Their wish was to be buried together at Bourne Veterans cemetery as there is not enough room at Forest Hills. My brother is in New England but my sister and I are stuck in Arizona and can’t afford the airfare or the hotel for the two of us. Any help will be greatly appreciated.
