There appears to be at least 3 men named Solomon Oppenheimer in Philadelphia and nearby areas, in the early 1900s. One of them was married to a woman named Harriet, a second Solomon was married to a woman with the maiden name Fanny Shoger, and a third Solomon was married to a woman named Bertha.

Which of these Solomons is the correct person? And what are the names of the children of the correct Solomon?
