Esteban and Martha had four (4) children: Rolando, Jun, Mark, and Hector. Rolando had a daughter, Edith, while Mark had a son, Philip. After the death of Esteban and Martha, their three (3) parcels of land were adjudicated to Jun. After the death of Jun, the properties passed to his surviving spouse Anita, and son Cesar. When Anita died, her share went to her son Cesar. Ten (10) years after, Cesar died intestate without any issue. Peachy, Anita's sister, adjudicated to herself the properties as the only surviving heir of Anita and Cesar. Edith and Philip would like to recover the properties claiming that they should have been reserved by Peachy in their behalf and must now revert back to them. Is the contention of Edith and Philip valid? (4%)
