From my own research several years ago, I knew that there were some Peirce girls related to my main line that had become Mormons, but I never really gave it much thought since they weren't in my direct line. A visitor to this site recenlty sent me an email asking about this line, so I decided to take a closer look. The Peirce family in question was that of Robert, son of Thomas Peirce and Margaret Trimble. Robert was born in 1797 and married Hannah Harvey in 1821. Both the Peirces and the Trimbles were prominent Quaker families, so it was a bit of a surprise to see that not just Robert and his family but his sister Esther Ann (1801-1858) as well, converted to Mormonism and settled in Utah. Not only did some of the Peirces become Mormons, a listing of some of their descendants reads a bit like a "Who's Who" of early LDS prominent pioneers!
