One need not in any way genetically or familially descend from such a person for him or her to be an elder/ancestor.
What European-like groups, in English, call “elders” and “ancestors” are basically two expressions of one form of being.
It simply does not work to say ancestors are dead and elders are alive, as this makes a separation that misrepresents the essential connection between the two in the first place.
Being alive or dead does not change their status as elders, or ancestors.
