Puzzle - Henry Storck

My grandfather's brother, Henry Storck, married in Manhattan in 1905, and moved to Newark, NJ sometime between the birth of his 6th child in 1920 and 7th child in 1925.  Henry and family are listed in Newark in the 1930 and 1940 census, and in 1942, Henry completed a WW2 draft registration, which lists his wife as contact.  

In 1947, their 3 sons appear in the Newark city directory listing The Storck Boys, a gasoline station. They have separate residential addresses, and only one is married: Silvin L., to Arline P. 

By 1952, the oldest son, Robert Quentin, has moved to Stockton, California where he spends the rest of his life, dying in 1993 at age 80. Although married several times, he does not father any children. 

Have been unable to trace the other 2 sons, nor connect any with more contemporary Storcks living in Newark area.
