From Clocks to Legacy: The Story of Johann Henrich Heilig and the Rittenhouse Connection

Johann Henrich Heilig, my 6th great-grandfather, was born in 1700 and married Susanna De Wees Rittenhausen in 1729. Susanna’s family was prominent in early American industry, particularly in the Rittenhouse paper mills, which I’ve written about previously. If you’re a descendant or admirer of the Rittenhouse legacy, I recommend exploring the Rittenhouse Family Descendants and Friends Facebook page and learning about their efforts to preserve this rich history. The Rittenhouse Town Board of Directors actively maintains the historic Homestead House (built in 1707), the surrounding village, and a barn constructed during the WPA era.

Henrich’s origins remain debated among historians. Earlier accounts suggest he was born in Hannover, Germany, while newer research points to Baden-Wuerttemberg. What we do know is that Johann arrived in Philadelphia in 1720 aboard the Polly. Since passenger lists weren’t required until 1727, his exact journey is pieced together through indirect evidence.

By April 11, 1747, Johann was officially naturalized as a resident of Pennsylvania, meeting the colonial requirement of seven years’ residency. By this time, he was known as Henry—a clockmaker by trade. Clockmaking was a respected profession during the 18th century, vital for navigation, surveying, and precise timekeeping.

Henry and Susanna initially settled in Cheltenham but later purchased land on the borders of Pennsburg and Upper Hanover Townships in Montgomery County in 1749 and 1750. This property, acquired from surveyor William Parsons (an associate of the Penn family), remained in the family for generations. Passing from Henrich to his son George, and later to George Jr., the land was eventually sold to the Hoch family in the 1860s. Remarkably, the Hoch family still owns the house today—a living testament to centuries of stewardship.

Before 1684, the Lenape Indians roamed the hills and fished the streams of the land on either side of the Perkiomen Creek. In 1684, the Indians lost this land when  William Penn purchased it for reportedly “two watch coats, four pairs of stockings and four bottles of cider.”  In time, Pennsylvania Germans settled in the area. Around 1840, the area now known as Pennsburg began to appear like a village.  The hub comprised a general store, a carpenter and blacksmith shop, and several houses.
Most of the land was owned by the Heilig Brothers.  They owned and resided in the oldest house in Pennsburg, located at Seminary and Fourth Streets. The Heilig Brothers took it upon themselves to refer to this village as “Heiligsville.” Residents had their ideas, and out of loyalty to the then Pennsylvania Senator, James Buchanan, wanted to name the area Buchanansville.

As the village grew, a meeting was held in 1843 at the Hilleg family store to decide on a permanent name and layout of boundary lines.  After a week-long, bitterly contested battle, it was finally decided to name the village “Pennsburg” after William Penn.

Henrich and Susannah had five children:

i. Heinrich Heilig, b. 1722, ii. Jurg George Heilig, b. 1720; d. 1796, Upper Hanover Township., iii. Johannes Heilig (Source: Willbook I – 1796, 149-150.).
iv. Anna Maria Heilig (Source: Willbook I – 1796, 149-150.), m. Michael Slonaker., v. Susanna Heilig (Source: Willbook I – 1796, 149-150.), b. 1726; m. Henry Deany.

Johannes or John changed the surname to Highley. The other children kept the German spelling of Heilig.

Henry was a clockmaker. He passed down the art of his clockmaking skills to his children and nephews. One of the most famous was David Rittenhouse, an avid astronomer; he built complicated astronomical clocks and orreries, or planetary models, that kept time and predicted celestial events.

Henry is listed in the U.S., Craftperson Files, 1600-1995.

Henry was buried along with his wife in the mostly Rittenhouse family cemetery, Methacton Mennonite Cemetery. Click here for a partial list of burials with links to tombstone photographs. Henrich’s and Susannah’s are below. This cemetery is located in Worcester Township, Montgomery County, PA.

A wonderfully thorough history is written by Linton E. Love, a descendant of the Rittenhouse family. In it are the descendants of Henry and Susannah. Linton has created a database extending from the 17th century up to the 21st century from Claus to his 12,810 descendants as of March 2005!

Johann Henrich Heilig’s story is one of perseverance, skill, and enduring family ties. From his arrival in Philadelphia to the land that remains in familial care, his legacy is woven into the fabric of American history. Whether as a skilled clockmaker or as part of the Rittenhouse connection, his contributions remind us of the resilience and dedication of early immigrants. By reflecting on his life, we not only honor his journey but gain inspiration for preserving our own family stories for generations to come. Do you have a Heilig clock? You might!
