My grandmother’s mother, Effie J. Rhining’s maternal grandparents were William Cowan (1815-1898) and Nancy Campbell Smith Parish Cowan (1823-1908) of Monmouth IL. Prior to now, my genealogy stopped with them. But I recently decided to take another look and was able to trace the Cowans back to Pennsylvania, where they settled in the Pequea Valley around 1720, after immigrating from Berwickshire, Scottish borderlands.
David W. Cowan (1790-1845)
William was the son of David W. Cowan (1790-1845) and Margaret Kyle (b. about 1795). David worked as a tanner and currier in Chester County, according to the biography on William that was published in1886.
David W. Cowan and Margaret Kyle were married 25 Sep 1812 at Upper Octorara Presbyterian Church, Parkesburg, Chester County, Pennsylvania. David was about 22 years old on their wedding day. The marriage was performed by Rev James Latta.

According to the church’s website, Upper Octorara Presbyterian Church (UOPC) was established in 1720 by a group of Scottish and Irish immigrants, including a number of Cowans– however they were not “our” Cowans.
Episcopalian Roots

David W. Cowan was born into an Episcopalian Scottish family but was baptized Presbyterian on October 10, 1813, one year after his marriage to Margaret Kyle.
David’s grandfather and great-grandfather, both also named David Cowan, were founding members of St. John’s Episcopal Church of Pequea, located in the Town of Compass, West Caln Township, Chester County. The family’s Episcopalian roots distinguished them from the unrelated Hugh Cowan family that settled in the Pequea Valley around the same time.
Scottish immigrants were more commonly Presbyterian; the Ulster Scots, also known as Scotch-Irish settlers, were primarily Presbyterians who had been driven to Ireland for different reasons. Some fled due to the War of the Three Kingdoms and the religious persecution of Scottish Covenanters, who had opposed the Crown in their fight for a Presbyterian Church of Scotland. Others were sent by King James as part of a colonization project designed to rid Ireland of the Irish people and Catholics. However, this plan largely failed, as the Irish resisted and drove many of the settlers out—either back to Scotland or onward to the American Colonies.
Unlike many of their countrymen, David W. Cowan’s forefathers were steadfast in their Episcopalian beliefs. Rather than joining the well-established Presbyterian church that stood practically in their backyard, they helped establish their own congregation and build St. John’s Episcopal Church.

1830 United States Census
The 1830 US Census recorded a David Cowan in Strasburg Township, Lancaster County. Pennsylvania. More research is needed to confirm whether this is the right person; David was a very popular name in the large, extended Pennsylvania Cowan clan. This could be David S. Cowan, son of Robert Cowan.
