Ralph and his wife, Raphael had one child, Sarajane. Sarajane married William Lecklider and their middle son, Steve now operates the orchard full time. The second and third generation fruit growers (William, Sarajane, and son Steve) took over Lehman's Orchard in 1992 and have since added many other fruit crops sold at the farm and at various Chicago farmer's markets.

In 1947, a mechanical pitting machine greatly improved sales and this machine is still used today.
