Where one places a grave site will determine who lands on it in the future. Often tombstones are forgotten along the path of life but left in a central area the memories can last many other lifetimes and leave a mark for the tribe they belonged too. Rachel’s tombstone was destine in such a place as it has been central to many in the Jewish tribe for many, many generations. G-D has a reason for everything even messages we understand way after our clock has passed on.
