Isaac Dull was listed in the 1820, 1830 and 1840 censuses for Windham Twp. John Christian Dull (Isaac's son) is listed in the 1830 and 1840 censuses for Windham Twp. I believe they lived near a place called Doll Mountain. This "mountain" is located on/near the Susquehanna River near Sugar Hollow, Jayne Pond and Grist Flat. It appears to be about 5 miles west of Tunkhanook (Sp?). Isaac and his wife Catharine sold their property, 102 acres, for $1000 to Benjamin Stemples 27 May 1844. Isaac also served as a Capt. in the U.S. army during the War of 1812. Any additional or substatiated information would be greatly appreciated.
