Hi Shmuel-Aharon - my source is an ancestry tree and the other daughter is listed as living so I cannot see the details so cannot add any more information to her.
My family is dna connected to them.
Unfortunately the abandoned geni tree had no dates entered so other than 3 names being the same (common ones like Sara/Sarah and Richard) it is not possible for a non curator to compare the living profiles to determine if the <private> was Randy which would add weight to them being the same tree.
My purpose in creating a discussion (rather than a curator request) was that someone connected/interested in the line in some future might be able to easily see the two trees and if they had more information they could request a merge.
