Maria and Lo were named for their paternal grandparents, Maria Dickinson Logan I and Albanus Charles Logan I, both of whom were shareholders of the Library Company. Two separate shares, Share 100 and Share 98, were passed through the Dickinson-Logan family. Share 100 originated on the Dickinson side with Maria and Lo’s great-grandfather, John Dickinson. John Dickinson was a lawyer and politician who served as Continental Congressman from Pennsylvania and Delaware. He also served in the Pennsylvania militia during the American Revolution and as a delegate to the U.S. Constitutional Convention of 1787. Many of his books and papers, including his funeral hatchment, reside in the Library Company’s collection.
Share 98 originated on the Logan side with Lo’s great-great-grandfather, William Logan (d. 1776). William Logan was the son of James Logan (1674-1751), whose extraordinary personal library of nearly 3,000 volumes opened as the Loganian Library in 1760. The Loganian Library merged with the Library Company in 1792, after the death of all the original trustees except James Logan’s son. The Library Company maintained the designation “Loganian” for acquisitions that complemented the original collection of James Logan. This enormous acquisition nearly doubled the holdings of the Library Company, making it the second largest library in the nation, after that of Harvard College. Among the marvels from the Loganian Library still on the Library Company’s shelves is the first copy of Newton’s Principia to touch the soil of the North American continent.
Maria and Lo’s grandfather Albanus I was the head of Stenton, the family’s Germantown estate. At Stenton he kept a large library which he adored. Upon his death he directed that his library “shall remain undivided during the lifetime of [his wife Maria I].” In 1871 (indeed after Maria I’s death), his grandson Lo would go on to expand the “Loganian Library” by donating 500 volumes from Stenton to the Library Company. The “Loganian Library” still constitutes a valuable part of the Library Company’s collection and is still in use today.
Albanus Charles Logan I and his wife Maria I instilled in their children and grandchildren a passion for education and history, and left behind a legacy of philanthropy.
