My first known Pierce ancestor was William K. Pierce, b. April 30, 1807, in PA of PA-born parents. He was living in Crawford Co., PA at least from 1840 on till his death Jan. 29, 1891, also in Crawford Co. PA. He married Cinderella (Dunn, we think) about 1835. She too was b. in PA of PA-born parents. There is an Asa Dunn just a few properties over from W. K. Pierce in the 1875 Historical Atlas of Crawford Co., PA, in Fairfield Township. I have a list of his 9 children and some of their spouses. Would love to connect with someone else researching this line. Sincerely, Linda Pierce Moore
