"According to the 1850 census, Mary E. Angle was born abt. 1833; Harriet born abt. 1838;  and Martha born about 1846.   With knowing this, they must be Joseph and Elizabeth's grandchildren, with the father dying between 1846 & 1850."   I agree the children were most apt to have been Joseph and Elizabeth's grandchildren but I disagree with your time frame for their father's death.   My notes on the ages and birth years for the Woodmancy children in 1850: Mary E - 17 Ct (1832/1833) - basically the same as yours Martha - 14 OH (1835/1836) Harriet - 12 OH (1837/1838) - basically the same as yours --Mary Angle - 37 Ct  (1812/1813) --Joseph Angle - 9  (1840/1841)     The 1839 marriage for Mary Woodmansee and Peter Angle found by Eliz is another indication, to me, that Mary was the mother of these children. (Did you note the month and day of this marriage? That information might eliminate any possibility that Mary was pregnant by her Woodmansee husband when she married Peter. Due to the given name of the first child born after their marriage plus my belief that Mary's deceased husband had been named Joseph, I wondered whether young Joseph, despite his Angle surname, might have been named for his biological father. Young Joseph could have been born shortly after June 1 in 1840.)   1840 Washington Co., Watertown twp. - Peter Angle Jr.'s household appeared to have the family, including Elizabeth, in his household. I presumed Mary was the female listed as 30-39, and a probable census error. (Wasn't Mary in her 40s in 1860?)   So - without more data the father of the children appears to have died sometime between 1837 and 1839.   If Mary Angle was Mary Perkins "of Groton," CT, then Elizabeth's son was named Joseph. Extrapolating from her 1850 age Mary would have been about 17 y/o at the time of the 1830 census. Betsy Woodmansee's son, the only child in her household, was listed as 15-19 in 1830 (he'd been 0-9 in 1820). Due to Betsy's husband's death their son may have been born earlier but would have been born no later than 1814. Mary and Joseph, both "of Groton" were married in October of 1830. One or both may have had a birthday between June 1 and their wedding.   When examining the early census households, 1790-1810, one of the questions that arose for me was whether Elizabeth had been widowed with a daughter, and perhaps a son, before her marriage to Joseph. You might call it the Hmmmmm response. In 1790 Elizabeth was about 18. Joseph certainly appeared to be married in 1790 with a son 15 or under and possibly a daughter (112). The only female in his 1800 household appeared closer to him in age. She was 45 or older. His 1810 household appeared to include Elizabeth but also had a female 10-15 (1794 -1800) and a male with the same birth range.    Ella
