Two years after his first arrival he returned briefly to Belgium, but in 1850 he crossed the Atlantic again, this time permanently. On June 22, 1852, he was united in marriage to Anna Helen Bekel at St. Francis Church in Taos. Their union was blessed with eleven children: Henry Joseph, Charles L., Peter J. Jr., Clem A., Emil J., August V., Otillia M., Sophia C., Joseph F., and Frank G. One child died in infancy, and Henry J. passed away on September 20, 1888.

Mrs. Anna Helen Dierckx continued to reside at the family home in Taos, serving as postmistress — an office that remained in the family continuously from 1854, except for two years during the Civil War.

Peter J. Dierckx was remembered as an excellent citizen and capable financier. At his death on April 10, 1886, he left behind a substantial estate, the result of disciplined effort and sound judgment. Beyond business, he was respected for his upright conduct in family, social, and civic life. A leading Democrat in Cole County, he actively supported the party throughout his lifetime — a commitment continued by his sons. He was also a devoted member of the Catholic Church.

The Civil War brought heavy financial losses and hardship. Union soldiers confiscated approximately 500 bushels of corn, valued at 25 cents per bushel, and took a prized mare — which was fortunately returned after the war. In July 1867 his barn was destroyed by fire, consuming all stored wheat, four horses, and a mule. Wheat at that time was valued at three dollars per bushel, flour at nine dollars and twenty-five cents per hundred pounds.

During the war he withdrew from commercial business, returning temporarily to merchandising after the devastating fire. Eventually he resumed farming — his preferred occupation — which he pursued until his death at the age of fifty-seven years and fifteen days.
