 Doyle died in August 1759, and Nicola married his second wife, Jane Bishop, on April 18, 1760. Their family decided to move to Philadelphia, Pennsylvania, and they arrived August 1766. Upon the arrival Nicola started his own dry goods store. This did not work, and he eventually opened a library in September 1767. It started with nearly 200 to 300 volumes before expanding to over 1,000. Throughout the next couple of years, Nicola moved the library to different spots before finally settling to Spruce Street and renaming it "General Circulating Library".
