I am trying to find the parents of my great, great grandmother, Nancy Ann Perry. She was born in Ohio on 5 May 1826 to a father from Pennsylvania and a mother from Ohio. She was married in Lawrence, Indiana (now part of Indianapolis) in 1850. Since 1830, the family of John and Drusilla Perry lived about a mile outside of Lawrence. They previously lived in Anderson Township of Hamilton County, Ohio. It appears that none of their children nor John and Druscilla were the parents of Nancy. It is be possible that she was a niece to John and Druscilla or possibly a granddaughter if they had a son who stayed in Ohio. According to the 1820, 1830 and 1840 censuses, there were only a few Perry families living in Anderson Township, Ann Perry(possibly a mother to John Perry), John Perry, William Perry and Joseph Perry. Joseph shows having a daughter of the right age in the 1840 census. I cannot find him in 1850 or 1860. So he may have died between 1840 and 1850.
Is there anyone who has information on Joseph and Sarah Perry, or that matter any of the other Perry's, which might connect my great great grandmother to any of them?
