We know the progenitor of the Straus family was Lazarus (born about 1715) but we don't know if he had any siblings. Most families at that time were quite large. As an example, Lazarus Straus, great grandson of the first Lazarus, (born 1809) was the oldest of 14. The first Lazarus and his wife Fegele had two sons, Jacob and Anschel. It is likely they had more children. We know about Moises Lazarus but don't know anything about his siblings or his parents. Again, given the size of families in those days, it is likely he was one of many. Our job will be to try to fill in the missing pieces of this fascinating puzzle.
