OBOLERS
In 1973 my father was handed a tree of descendants of Avrum and Tamara Oboler, each born 1804, to pass down to me. This tree was created a couple of years earlier by Alfred Oboler who apparently knew of my interest in family trees. The Oboler tree was apparently first created by Oboler descendants in New York at some time after WWII. Ever since, I have kept this tree as up-to-date as I could. Today two others are involved in this effort: Ed Rappaport, a grandchild of Max Oboler’s oldest brother Louis (who with his wife Vera were my godparents) and John Cornet, a more distant cousin. The three of us are descended from three different children of the progenitors Avrum and Tamara; we know of no descendants of a possible fourth child.
A large tree including information on all deceased Oboler cousins known to us, is on MyHeritage.com, managed by Ed Rappaport. My version of the Oboler tree, with over 2100 named descendants and spouses, is on my computer and is shared only with family.
