I have a copy of the will of Robert Lewis of Warminster Twp, Bucks Co. PA. The will is dated Oct. 12, 1841 and was proven on April 13, 1850. Children mentioned are David, Charles, Phebe, Sarah, Mary, Ann and Hester. Also mentioned are son's-in-law Hiram Yerkes and Isaac Harding. From the 1850 census, I believe that Hiram was married to Ann, and Isaac was married to Mary.
I believe that the son David might be my g-g-g-grandfather. If anyone can help fill in any details I would be very grateful. Of course, I'm willing to share any and all information I have on David K. Lewis and his descendents.
