Hi there,
Johannes Elbers was the brother of my Great-Grandmother Margje Elbers. She and her husband Annerie de Vries became guardians over their children when Johannes past away early in 1884.
Meanwhile maybe you have found what you were looking for in your question. I noticed Alle Elbers was responding, he knows as much and more about the Elbers. If not, do not hesitate to contact me.
