I believe the censuses indicate that Williston and Polly likely had three daughters with them in Schuyler Co in 1830. Demetrious that married Hezekiah Wilcox was listed as age 15-20 in 1840, so she was born between 1820-25. Maria Owen was age 17 in 1850, born in Ohio about 1833. There was also a marriage of a Harriet West to John Justus on 21 Dec 1843 - in the 1850 census, Harriet was age 18, born in Ohio about 1832. I would think these three ladies might be the three daughters listed in 1840. Apparently they had no sons.
