The business was eventually taken over by Leroy Allen's son, Kenneth L. Allen (1916-2002), around 1950. The company purchased trees on private lots, cut the timber, and contracted to make lumber into crates and boxes for product packaging and shipping. They also operated a commercial lumber yard on Allen Street in Rochester.
