Leopold (Lebel Löbel) Ledermann died 1877, possibly fighting in a war. He may have been a sergeant in the Austro-Hungarian army judging by his uniform (tho family history said Prussian). His widow Fanny (Feigele) Liebchen Ledermann (cousin?) emegrated to Newark NJ. His son, Albert (Abraham) Ivan Lederman (1871-1963), had emegrated first (sneaking across Germany to Hamburg to catch a ship over) and his relatives followed. Leopold's parents were Zve Lederman and Julia Henzler (both born about 1840s?). Fanny's parents were Löbel (Lebel) Ledermann and Hanna (Handel/Anna) Weiss of Kenpo. Hanna's parents may have been Wolff Alexander Weiss and Lea Rosalie Hirschel. Lea's parents: Hirschel Abraham Hirschel (1780) and Rachel (1785).
