My records show that Tenia (short for Christiana) was Mary Markey's sister. The Frantz woman married an Ikenberger (who knows what the original spelling was for that last name). Among John and Christiana's other children are John Isenbarger (my direct ancestor) who married Elizabeth Ditmore, one of the three George Icenbargers I'm trying to sort out, and Hester Isenbarger who married a Norris. After John's death (sometime before 1840 as Christiana is head of family in the 1840 census), Christiana married Jacob Fry (1843? in Clark Co, Ohio). She, Jacob and Hester (listed as Cristena and Hetta) were in the 1850 census in Clay, Montgomery, Ohio.
Henry and John were brothers; Christiana and Mary were sisters.
